                           for the securities underlying the convertible note,
                           presented in a table with the following information
                           disclosed separately [in this comment, the reference
                           to "securities underlying the convertible debenture
                           or convertible preferred stock" means the securities
                           underlying the debenture or preferred that may be
                           received by the persons identified as selling
                           shareholders]:

                                                                          Page 2

                                    if the conversion price per share is set at
                                    a fixed price, use the price per share
                                    established in the convertible debenture or
                                    preferred stock; and

                                    if the conversion price per share is not set
                                    at a fixed price and, instead, is set at a
                                    floating rate in relationship to the market
                                    price of the underlying security, use the
                                    conversion discount rate and the market rate
                                    per share on the date of the sale of the
                                    convertible debenture or preferred stock and
                                    determine the conversion price per share as
                                    of that date;

                           the total possible shares underlying the convertible
                           debenture (assuming no interest payments and complete
                           conversion throughout the term of the note);

                           the combined market price of the total number of
                           shares underlying the convertible debenture,
                           calculated by using the market price per share on the
                           date of the sale of the convertible note and the
                           total possible shares underlying the convertible
                           debenture;

                           the total possible shares the selling shareholders
                           may receive and the combined conversion price of the
                           total number of shares underlying the convertible
                           debenture or preferred stock calculated by using the
                           conversion price on the date of the sale of the
                           convertible debenture or preferred stock and the
                           total possible number of shares the selling
                           shareholders may receive; and

                           the date of the sale of the convertible debenture and
                           preferred stock, calculated by subtracting the total
                           conversion price on the date of the sale of the
                           convertible debenture or preferred stock from the
                           combined market price of the total number of shares
                           underlying the convertible debenture or preferred
                           stock on that date.

                  If there are provisions in the convertible debentures or in
                  the convertible preferred stock that could result in a change
                  in the price per share upon the occurrence of certain events,
                  please provide additional tabular disclosure as appropriate.
                  For example, if the conversion price per share is fixed unless
                  and until the market price falls below a stated price, at
                  which point the conversion price per share drops to a lower
                  price, please provide additional disclosure.


                                                                          Page 3

                           subject to the transaction immediately prior to the

                  COMPANY RESPONSE:
                  Prior to November 22, 2006, there had been no prior securities
                  transactions between Catuity (or any of its predecessors) and
                  the Selling Security Holders, any affiliates of the Selling
                  Security Holders, or any person(s) with whom any of the
                  Selling Security Holders had a contractual relationship
                  regarding the transaction.

         8.       SEC COMMENT: Please provide us, with a view toward disclosure
                  in the prospectus, with tabular disclosure comparing:

                           the number of shares outstanding prior to the
                           convertible debenture and Preferred stock transaction
                           that are held by persons other than the selling
                           shareholders, affiliates of the company, and
                           affiliates of the selling shareholders;

                           the number of shares registered for resale by the
                           selling shareholders or affiliates of the selling
                           shareholders in prior registration statements;

                           the number of shares registered for resale by the
                           selling shareholders or affiliates of the selling
                           shareholders that continue to be held by the selling
                           shareholders or affiliates of the selling
                           shareholders;

                           the number of shares that have been sold in
                           registered resale transactions by the selling
                           shareholders or affiliates of the selling
                           shareholders; and

                           selling shareholders in the current transaction.

                  In this analysis, the calculation of the number of outstanding
                  shares should not include any securities underlying any
                  outstanding convertible securities, options, or warrants.

                  COMPANY RESPONSE:
                  We have added tabular disclosure of the number of common
                  shares outstanding prior to the Convertible Debentures and
                  Preferred Stock transaction, the number of common shares
                  previously registered for resale by the Selling Security
                  Holders, and the number of common shares being registered on
                  behalf of the Selling Security Holders in the current
                  transaction, per the Staff's suggestion. Reference is made to
                  the table included on page 44 of the registration statement
                  titled "Supplemental Information Regarding Outstanding Common
                  Stock".

                           whether the issuer has the intention, and a
                           reasonable basis to believe that it will have the
                           financial ability, to make all payments on the
                           overlying securities; and

                           whether - based on information obtained from the
                           selling shareholders - any of the selling
                           shareholders have an existing short position in the
                           company's common stock and, if any of the selling
                           shareholders have an existing short position in the
                           company's stock, the following additional
                           information:

                                    short position to the date of the
                                    announcement of the convertible debenture
                                    and convertible preferred stock transaction
                                    and the filing of the registration statement
                                    (e.g., before or after the announcement of
                                    such transaction, before the filing or after
                                    the filing of the registration statement,
                                    etc.).

                  COMPANY RESPONSE:
                  In the short-term Catuity has the intention, and a reasonable
                  basis to believe that it will have the ability, to make all
                  payments on the overlying securities. However, as noted in
                  Catuity's 10-KSB filed April 2, 2007, and consistent with the
                  disclosures regarding the need for additional financing in
                  Catuity's second and third quarter 10-QSBs filed August 14,
                  2006 and November 14, 2006, respectively, additional financing
                  will be required, likely by mid-2007, in order to meet
                  liquidity needs. The liquidity needs include scheduled debt
                  service and dividend payments.

                  The Company has requested and has received, from each selling
                  security holder, confirmation that the selling security
                  holders do not have an existing short position in Catuity's
                  common stock.

         10.      SEC COMMENT: Please provide us, with a view toward disclosure
                  in the prospectus, with:

                           a materially complete description of the
                           relationships and arrangements that have existed in
                           the past three years or are to be performed in the
                           future between the issuer (or any of its
                           predecessors) and the selling shareholders, any
                           affiliates of the selling shareholders, or any person
                           with whom any selling shareholder has a contractual
                           relationship regarding the transaction (or any
                           predecessors of those persons) - the information
                           provided should include, in reasonable detail, a
                           complete description of the rights and obligations of
                           the parties in connection with the sale of the
                           convertible notes; and


                                                                          Page 8


                           copies of all agreements between the issuer (or any
                           of its predecessors) and the selling shareholders,
                           any affiliates of the selling shareholders, or any
                           person with whom any selling shareholder has a
                           contractual relationship regarding the transaction
                           (or any predecessors of those persons) in connection
                           with the sale of the convertible notes.

                  If it is your view that such a description of the
                  relationships and arrangements between and among those parties
                  already is presented in the prospectus and that all agreements
                  between and/or among those parties are included as exhibits to
                  the registration statement, please provide us with
                  confirmation of your view in this regard.

                  COMPANY RESPONSE: Other than the relationships and
                  arrangements described in the prospectus, Catuity has not had
                  any, and does not have any contracts for, relationships or
                  arrangements with the selling shareholders.

                  Please see the disclosure in the prospectus regarding the
                  financing and the rights and obligations of the parties in
                  connection with the sale of the convertible notes.

                  Copies of all agreement between Catuity and the selling
                  shareholders, any affiliates of the selling shareholders, and
                  any person with whom any selling shareholder has a contractual
                  relationship are included as exhibits to Catuity's Form 8-K
                  filed November 22, 2006, which is incorporated into the
                  registration statement by reference.

         11.      SEC COMMENT: Please provide us, with a view toward disclosure
                  in the prospectus, with a description of the method by which
                  the company determined the number of shares it seeks to
                  register in connection with this registration statement. In
                  this regard, please ensure that the number of shares
                  registered in the fee table is consistent with the shares
                  listed in the "Selling Shareholders" section of the
                  prospectus.

                  COMPANY RESPONSE:
                  This registration covers only a portion of the shares issuable
                  on conversion of the Convertible Debentures and Preferred
                  Stock. The warrant shares are not included in the registration
                  statement. The number of shares being registered was computed
                  based upon 30% of the total common shares outstanding held by
                  non-affiliates of the company as of March 31, 2007, and the
                  shares listed in the "Selling Security Holders" section
                  includes both the shares being registered as well as the
                  warrant shares.

                  The number of shares of common stock issuable under the
                  Convertible Debentures is equal to the original principal
                  amount of each debenture divided by the conversion price. The
                  original principal amounts of the Convertible Debentures are
                  $1,111,112.00 and $688,888.00, respectively, and the
                  conversion price is $3.25. Accordingly, the number of shares
                  of common stock issuable upon conversion of the


                                                                          Page 9


                  Convertible Debentures equals (1,111,112/3.25) and
                  (688,888/3.25) or 341,881 and 211,966, respectively (rounded
                  to the nearest whole number). Therefore, a total of 553,847
                  shares of common stock are issuable upon conversion of the
                  Convertible Debentures.

                  Pursuant to the Certificate of Designations, the number of
                  shares of common stock issuable upon conversion of each of the
                  Preferred Shares is equal to the "Stated Value" of each of the
                  Preferred Shares, $1,000.00, divided by the conversion price,
                  $3.25. Thus, 307.6923 shares of common stock are issuable upon
                  conversion of each of the Preferred Shares. Gottbetter Capital
                  Master, Ltd. was issued 432.10 Preferred Shares and
                  BridgePointe Master Fund Ltd. was issued 267.90 Preferred
                  Shares. Upon conversion of the Preferred Shares, then,
                  Gottbetter Capital Master and BridgePointe Master Fund Ltd.
                  would be issued 132,954 and 82,431 shares of common stock,
                  respectively (rounded to the nearest whole number), or 215,385
                  shares collectively.

                  Accordingly, Catuity initially sought to register 553,847
                  shares of its common stock for issuance upon conversion of
                  the Senior Notes and 215,385 shares of its common stock for
                  issuance upon conversion of the Preferred Shares. However,
                  based on conversations with the SEC staff subsequent to
                  receipt of the comment letter, Catuity has decided to reduce
                  the total number of registered shares, such that the total
                  number of shares registered under the registration statement
                  would be equal or less than 30% of the total outstanding
                  shares of common stock held by non-affiliates. Thus, Catuity
                  seeks to register a total of 621,218 shares of its
                  common stock.

                  In our initial filing, we rounded "down" to the nearest whole
                  number, rather than rounding "up." Rounding up, we have 2 more
                  shares being registered. The additional registration fee for
                  these 2 additional shares is less than $0.01, so the
                  registration fee table should reflect the new number of
                  shares, but no change in the fee due and paid.

                  of the prospectus beginning on page 44 of the registration
                  statement will be presented as follows:

Exhibit 5, Opinion of Jaffe, Raitt, Heuer & Weiss

         15.      SEC COMMENT: Counsel states that the 769,230 shares being
                  registered for resale "will have been duly authorized". If the
                  issuance of the shares has been duly authorized, please
                  express that as an action that has already been taken. If the
                  authorization has not yet occurred, clarify what remains to be
                  accomplished and the assumptions that are made in concluding
                  that the issuance "will have been duly authorized".


                                                                         Page 11


                  COMPANY RESPONSE:
                  Counsel's intent was to express that authorization is
                  complete, by using the future-perfect tense. For clarity,
                  counsel has revised its opinion to clarify that the action
                  authorizing the issuance of the shares has already been taken.

         16.      SEC COMMENT: Please also confirm whether the opinion regarding
                  the common shares to be issued reflects the Delaware state
                  constitution, state code, state court decisions, and decisions
                  of the state supreme court.

                  COMPANY RESPONSE:
                  Counsel's opinion is not limited, and reflects the Delaware
                  state constitution, state code, state court decisions, and
                  decisions of the state supreme court.



         In conversations with the Staff subsequent to the issuance of the
comment letter, Staff noted a concern as to the applicability of Rule 415 for
this registration. At the invitation of the Staff, we would like to take this
opportunity to explicitly address whether the offering is appropriately
characterized as a secondary offering that is eligible to be made on a shelf
basis under Rule 415(a)(1)(i).

         We respectfully advise the Staff that we have analyzed and determined
that the offering being registered on Form SB-2 is appropriately characterized
as a secondary offering that is eligible to be made on a shelf basis under Rule
415(a)(1)(i) for the following reasons:

         Rule 415(a)(1)(i) provides that:

                  "(a)     Securities may be registered for an offering to be
                           made on a continuous or delayed basis in the future.
                           Provided, that:

                           (1)      The registration statement pertains only to:

                                    (i)      Securities which are to be offered
                                             or sold solely by or on behalf of a
                                             person or persons other than the
                                             registrant, a subsidiary of the
                                             registrant or a person of which the
                                             registrant is a subsidiary..."

         We believe the SB-2 we seek to file to effect the offering satisfies
Rule 415(a)(1)(i) because it registers securities on behalf of persons other
than Catuity, a subsidiary of Catuity or a person of which Catuity is a
subsidiary.

Background: The Nature of the Transaction

         The convertible notes and convertible preferred shares overlying the
shares being registered for resale under the SB-2 (the "Offered Shares") were
sold or issued to two accredited investors with passive investment intent in a
valid and customary Section 4(2) transaction negotiated at arms'

                                                                         Page 12


length and consummated on November 22, 2006 (the "Private Placement"). The
Offered Shares are the shares that are issuable to the investors upon conversion
of the convertible notes and convertible preferred shares. Notably, none of the
Offered Shares were issued or are issuable pursuant to any form of equity line
arrangement. Further, the Private Placement has been completed and is not
ongoing -- the investors' funds were fully committed, at market risk and
irrevocably paid at closing.

Analysis: Secondary versus Primary Offering

         Item D.29 of the SEC's 1997 Manual of Publicly Available Telephone
Interpretations sets forth six factors that an issuer should analyze to
determine whether an offering is a secondary offering within the meaning Rule
415. These factors include: how long the selling stockholders have held the
shares; the circumstances under which they received them; their relationship to
the issuer; the amount of shares involved; whether the sellers are in the
business of underwriting securities; and finally, whether under all the
circumstances, it appears that the seller is acting as a conduit for the issuer.

         Our analysis of these factors is set forth below. We believe the
analysis confirms that the sale of the Offered Shares is appropriately
characterized as a secondary offering eligible to be made on a shelf basis under
Rule 415(a)(1)(i).

         1.  How long the selling stockholders have held the shares:

         The 621,218 shares being registered on the SB-2 are issuable to the
         selling stockholders pursuant to securities that have been held for
         more than four months.

         Except for days on or following a public announcement, the trading
         volume for our common stock is generally very modest, and we
         believe that the sale into the public market of any significant portion
         of the 621,218 shares being registered would dramatically reduce the
         price the selling stockholders would receive, thereby severely reducing
         the value of their investment. Further, given that the conversion price
         of the convertible notes and convertible preferred shares is currently
         significantly above the recent trading price of our common stock, we
         believe it is unlikely that the selling stockholders can or will
         convert to common stock and sell shares pursuant to the registration
         statement in the near future, thereby likely extending their holding
         period with respect to the securities overlying the Offered Shares.

         2.  Circumstances under which the investors received their shares:

         As described above, the investors received the convertible notes and
         convertible preferred shares overlying the Offered Shares pursuant to a
         valid and completed private placement transaction. The investors have
         been at market risk for their entire investment since the date of the
         closing of the Private Placement. None of the Offered Shares were
         issued or are issuable pursuant to any form of equity line arrangement.
         We will receive no proceeds from the sale of any of the Offered Shares
         by the selling stockholders. The investors could not, after they paid
         for and acquired the convertible notes and convertible preferred shares
         in the


                                                                         Page 13


         Private Placement, immediately turn around and sell them in the public
         market. The certificates representing the convertible notes and
         convertible preferred shares all bear restrictive legends restricting
         transfer absent registration or the availability of an exemption from
         registration.

         3.  The Investors' relationship to the issuer:

         The selling stockholders in the SB-2 are private investment funds.
         Prior to the negotiations resulting in the consummation of the Private
         Placement, we had no relationships or arrangements whatsoever with the
         selling stockholders. Accordingly, we respectfully submit that none of
         the shares being registered for resale under the SB-2 are being sold by
         or on our behalf.

         4.  The amount of shares involved:

         On March 31, 2007 2,317,486 shares of our common stock were
         outstanding, 2,070,725 of which were held by investors deemed to be
         non-affiliates. Therefore, the 621,218 shares we seek to register
         pursuant to the SB-2 represent approximately:

                  -        30.0%, as a percentage of the total outstanding
                           shares held by non-affiliates at march 31, 2007;

                  -        26.81%, as a percentage of the total outstanding
                           shares held by all stockholders at March 31,2007;
                           and

                  -        21.14%, as a percentage of the total outstanding
                           shares at March 31, 2007 plus the Offered Shares

         5.  Whether the sellers are in the business of underwriting securities.

         As mentioned above, the selling stockholders in the SB-2 are private
         investment funds. To our knowledge and based on inquiry, none of the
         selling stockholders is a registered broker-dealer or an affiliate of
         a broker-dealer. Broadband Capital Management, LLC, the placement
         agent for the Private Placement, is a registered broker-dealer. Each
         of the selling stockholders has advised us that it purchased or
         acquired the shares in the ordinary course of business and that at the
         time of the purchase of the securities overlying the Offered Shares, it
         had no agreements or understandings, directly or indirectly, with any
         person to distribute the securities. To our knowledge, neither of the
         selling stockholders is in the business of underwriting securities. The
         sale of the convertible notes and convertible preferred shares was not
         conditioned on the prior effectiveness of a registration statement or
         on the selling stockholder's ability to sell the Offered Shares, the
         convertible notes or the convertible preferred shares.

         Moreover, Gottbetter Capital Master, Ltd., the lead investor in the
         transaction, invests in a number of companies and, upon inquiry, has
         confirmed to us that their historical practice has been to hold their
         investment positions, rather than rapidly buy and sell in order to
         take advantage of short-term price fluctuations. For this reason,
         and the others discussed above, we respectfully



                                                                         Page 14


         submit that the selling stockholders are not underwriters and were not
         acting as underwriters with respect to the Private Placement.

         6. Whether under all the circumstances it appears that the seller is
         acting as a conduit for the issuer:

         Neither of the selling stockholders is acting as a conduit for Catuity.
         Acting as a conduit for the offer and sale of our securities would not
         be in the best interests of the selling stockholders, as they would
         currently be unable to sell the shares of common stock issuable upon
         conversion of their convertible securities for a comparable price in
         the market. Further, even if a selling stockholder desired to act as a
         conduit for Catuity, it would be difficult because the trading volume
         of our common stock is generally very modest.

         Each selling stockholder is an investor and made an independent
         decision to acquire the securities overlying the Offered Shares. The
         selling stockholders are not in the underwriting business. The Private
         Placement was negotiated at arm's length terms with immediate and
         continuing economic and market risks.
