                                     WARRANT

This warrant certificate (the "Warrant Certificate") certifies that Raymond A.
Roncari or registered assigns, is the registered holder of warrants to purchase,
at any time commencing on March 3, 1999 and continuing until 5:00 P.M., United
States Eastern Time Zone, on March 3, 2004 (the "Expiration Date"), up to 12,500
fully-paid and non-assessable shares, subject to adjustment in accordance with
Article 7 hereof (the "Warrant Shares"), of the common stock, par value $.001
per share (the "Common Stock"), of American Card Technology, Inc., a Delaware
corporation (the "Company"), subject to the terms and conditions set forth
herein.  The warrants represented by this Warrant Certificate and any warrants
resulting from a transfer or subdivision of the warrants represented by this
Warrant Certificate shall sometimes hereinafter be referred to, individually, as
a "Warrant" and, collectively, as the "Warrants."  



     1.   EXERCISE OF WARRANTS.  
          (a)  Each Warrant is initially exercisable to purchase one Warrant
Share at an initial exercise price per Warrant Share of eighty percent (80%) of
the per share Market Price (as defined in Section 1(b) hereof) of the Common
Stock on the exercise date, subject to adjustment as set forth in Article 7
hereof, payable in cash or by check to the order of the Company, or any
combination of cash or check.  Upon surrender of this Warrant Certificate with
the annexed Form of Election to Purchase duly executed, together with payment of
the Exercise Price (as hereinafter defined) for the Warrant Shares purchased, at
the Company's principal offices (presently located at 1355 Terrell Mill Road,
Building 1462, Suite 200, Marietta, Georgia 30067) the registered holder hereof
(the "Holder" or "Holders") shall be entitled to receive a certificate or
certificates for the Warrant Shares so purchased.  The purchase rights
represented by this Warrant Certificate are exercisable at the option of the
Holder hereof, in whole or in part (but not as to fractional shares of Common
Stock).  In the case of the purchase of less than all the Warrant Shares
purchasable under this Warrant Certificate, the Company shall cancel this
Warrant Certificate upon the surrender thereof and shall execute and deliver a
new Warrant Certificate of like tenor for the balance of the Warrant Shares
purchasable hereunder.

          (b)  "Market Price" at any date (the "Applicable Date") shall be
deemed to be the average of the last reported sale price, or, in case no such
reported sale takes place on such day, the average of the last reported sale
prices for the last three trading days, in either case as officially reported by
the principal securities exchange on which the Common Stock is listed or
admitted to trading or as reported in the NASDAQ National Market System, or, if
the Common Stock is not listed or admitted to trading on any national securities
exchange or quoted on the NASDAQ National Market System, the closing bid price
as furnished by the National Association of Securities Dealers, Int. through
NASDAQ or similar organization if NASDAQ is no longer reporting such
information, or if the Common Stock is not quoted on NASDAQ or a similar
organization, as determined in good faith by resolution of the Board of
Directors of the Company, based on the best information available to it for the
day immediately preceding the Applicable Date, the day of the Applicable Date
and the day immediately after the Applicable Date.

     2.   CASHLESS EXERCISE.  At any time until the Expiration Date, the Holder
may, at its option, exchange the Warrants represented by this Warrant
Certificate, in whole or in part (a "Warrant Exchange"), into the number of
Warrant Shares determined in accordance with this Section 2, by surrendering
this Warrant Certificate at the principal office of the Company accompanied by a
notice stating such Holder's intent to effect such exchange, the number of
Warrant Shares to be exchanged and the date on which the Holder requests that
such Warrant Exchange occur (the "Notice of Exchange").  The Warrant Exchange
shall take place on the date specified in the Notice of Exchange or, if later,
the date the Notice of Exchange is received by the Company (the "Exchange
Date").  Certificates for the Warrant Shares issuable upon such Warrant Exchange
and, if applicable, a new Warrant Certificate (a "Remainder Warrant
Certificate") of like tenor evidencing the Warrants which were subject to the
surrendered Warrant Certificate and not included in the Warrant Exchange, shall
be issued as of the Exchange Date and delivered to the Holder within three (3)
business days following the Exchange Date.  In connection with any Warrant
Exchange, the Holder's Warrant Certificate shall represent the right to
subscribe for and acquire (I) the number of Warrant Shares (rounded to the next
highest integer) equal to (A) the number of Warrant Shares specified by the
Holder in its Notice of Exchange (the Total Warrant Share Number") less (B) the
number of Warrant Shares equal to the quotient obtained by dividing (i) the
product of the Total Warrant Share Number and the existing Exercise Price per
Warrant 



Share by (ii) the current Market Price (as hereinafter defined) of a
share of Common Stock, and (II) a Remainder Warrant Certificate, if applicable. 

     3.   ISSUANCE OF CERTIFICATES.  Upon the exercise of the Warrants, the
issuance of certificates for the Warrant Shares purchased pursuant to such
exercise shall be made forthwith (and in any event within five (5) business days
thereafter) without charge to the Holder thereof including, without limitation,
any tax which may be payable in respect of the issuance thereof, and such
certificates shall (subject to the provisions of Article 4 hereof) be issued in
the name of, or in such names as may be directed by, the Holder thereof;
provided, however, that the Company shall not be required to pay any tax which
may be payable in respect of any transfer involved in the issuance and delivery
of any such certificates in a name other than that of the Holder and the Company
shall not be required to issue or deliver such certificates unless or until the
person or persons requesting the issuance thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid.

     The Warrant Certificates and, upon exercise of the Warrants, the
certificates representing the Warrant Shares shall be executed on behalf of the
Company by the manual or facsimile signature of those officers required to sign
such certificates under applicable law.

     The Warrant Certificates and, upon exercise of the Warrants, in part or in
whole, certificates representing the Warrant Shares shall bear a legend
substantially similar to the following:

     "The securities represented by this certificate and/or the securities
issuable upon exercise thereof have not been registered under the Securities
Act-of 1933, as amended ("Act"), and may not be offered or sold except (i)
pursuant to an effective registration statement under the Act, (ii) to the
extent applicable, pursuant to Rule 144 under the Act (or any similar rule under
such Act relating to the disposition of securities), or (iii) upon the delivery
by the holder to the issuer of an opinion of counsel, reasonably satisfactory to
counsel to the issuer, stating that an exemption from registration under such
Act is available."

     4.   RESTRICTION ON TRANSFER OF WARRANTS.  The Holder of this Warrant
Certificate, by its acceptance thereof, covenants and agrees that the Warrants
and the Warrant Shares issuable upon exercise of the Warrants are being acquired
as an investment and not with a view to the distribution thereof.

     5.   REGISTRATION RIGHTS.  In the event that, at some date after the
closing of an initial public offering of the Company's securities, the Company
determines to sell securities of the Company, for its own account or for the
account of others, in a registered public offering involving an underwriting,
the Company shall give prompt written notice thereof to the Holder, and if the
Holder shall so request in writing within twenty (20) days after receipt of any
such notice, the Company shall include in such registration all Warrant Shares
that the Holder so requests to be registered thereunder.  The Company, at the
written request of the underwriters, may limit such sales under any registration
statement.  The Company and the Holder shall provide the underwriters with all
requisite indemnities, comfort letters, or such other documents as such
underwriters may request.  The Company shall bear all of the expenses of any
such registration and sale, except that the Holder shall bear and pay (i) the
underwriters' discount attributable to the Warrant Shares sold by the Holder,
and (ii) Holder's attorney's fees.



     6.   PRICE.

          6.1  INITIAL AND ADJUSTED EXERCISE PRICE.  The initial exercise price
of each Warrant shall be eighty percent (80%) of the per share Market Price of
the Common Stock on the exercise date, per Warrant Share.  The adjusted exercise
price shall be the price which shall result from time to time from any and all
adjustments of the initial exercise price in accordance with the provisions of
Article 7 hereof.

          6.2  EXERCISE PRICE.  The term "Exercise Price" herein shall mean the
initial exercise price or the adjusted exercise price, depending upon the
context.

     7.   ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES.

          7.1  DIVIDENDS AND DISTRIBUTIONS.  In case the Company shall at any
time after the date hereof pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock, then upon such dividend or distribution,
the Exercise Price in effect immediately prior to such dividend or distribution
shall be reduced to a price determined by (i) dividing an amount equal to the
total number of shares of Common Stock outstanding immediately prior to such
dividend or distribution multiplied by the Exercise Price in effect immediately
prior to such dividend or distribution by (ii) the total number of shares of
Common Stock outstanding immediately after such issuance or sale.  For purposes
of any computation to be made in accordance with the provisions of this Article
7.1, the shares of Common Stock issuable by way of dividend or distribution
shall be deemed to have been issued immediately after the opening of business on
the date following the date fixed for determination of shareholders entitled to
receive such dividend or distribution.

          7.2  SUBDIVISION AND COMBINATION.  In case the Company shall at any
time subdivide or combine the outstanding Common Stock, the Exercise Price shall
forthwith be proportionately decreased in the case of subdivision or increased
in the case of combination.

          7.3  ADJUSTMENT IN NUMBER OF WARRANT SHARES.  Upon each adjustment of
the Exercise Price pursuant to the provisions of this Article 7, the number of
Warrant Shares issuable upon the exercise of each Warrant shall be adjusted to
the nearest full share of Common Stock by multiplying a number equal to the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of the Warrants immediately prior to such
adjustment and dividing the product so obtained by the adjusted Exercise Price.

          7.4  RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.  In case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in nominal value to no nominal value, or from no nominal value to
nominal value, or as a result of a subdivision or combination), or in the case
of any consolidation of the Company with, or merger of the Company into, another
corporation (other than a consolidation or merger in which the Company is the
surviving corporation and which does not result in any reclassification or
change of the outstanding shares of Common Stock, except a change as a result of
a subdivision or combination of such shares or a change in nominal value, as
aforesaid), or in the case of a sale or conveyance to another corporation of the
property of the Company as an entirety, the Holder shall thereafter have the
right to purchase the kind and. number of shares of stock and other securities
and property receivable upon such reclassification, change, consolidation,
merger, sale or conveyance as if the Holder were the owner of the Warrant Shares
issuable upon exercise of the 



Warrants immediately prior to any such events at a price equal to the product
of (x) the number of Warrant Shares issuable upon exercise of the Warrants
and (y) the Exercise Price in effect immediately prior to the record date for
such reclassification, change, consolidation, merger, sale or conveyance as
if such Holder had exercised the Warrants.

          7.5  DETERMINATION OF OUTSTANDING COMMON STOCK.  The number of shares
of Common Stock at any one time outstanding shall include the aggregate number
of shares issued or issuable upon the exercise of outstanding options, rights
and warrants and upon the conversion or exchange of outstanding convertible or
exchangeable securities.

     8.   REDEMPTION.  The Warrants are redeemable by the Company in whole or in
part, on not less than thirty (30) days, prior written notice at a redemption
price of $.10 per Warrant at any time commencing March 3, 2000, provided that
the closing bid quotation price of the Common Stock on each of the twenty (20)
trading days ending on the third day prior to the day on which the Company gives
notice of redemption has been at least $18.00.  The redemption notice shall be
mailed to the Holders of the Warrants at their addresses appearing in the
Warrant register.  Holders of the Warrants will have exercise rights until the
close of business on the date fixed for redemption.

     9.   EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.  This Warrant
Certificate is exchangeable without expense, upon the surrender hereof by the
registered Holder at the principal executive office of the Company, for a new
Warrant Certificate of like tenor and date representing in the aggregate the
right to purchase the same number of Warrant Shares in such denominations as
shall be designated by the Holder thereof at the time of such surrender.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of this Warrant
Certificate, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

     10.  ELIMINATION OF FRACTIONAL INTERESTS.  The Company. shall not be
required to issue certificates representing fractions of shares of Common Stock
and shall not be required to issue scrip or pay cash in lieu of fractional
interests, it being the intent of the parties that all fractional interests
shall be eliminated by rounding any fraction up, if such fraction is greater
than one-half, or down, if such fraction is equal to or less than one-half, to
the nearest whole number of shares of Common Stock to which the Holder is
otherwise entitled.

     11.  RESERVATION OF SHARES.  The Company covenants and agrees that it will
at all times reserve and keep available out of its authorized share capital,
solely for the purpose of issuance upon the exercise of the Warrants, such
number of shares of Common Stock as shall be equal to the number of Warrant
Shares issuable upon the exercise of the Warrants, for issuance upon such
exercise, and that, upon exercise of the Warrants and payment of the Exercise
Price therefor, all Warrant Shares issuable upon such exercise shall be duly and
validly issued, fully paid, nonassessable and not subject to the preemptive
rights of any shareholder.

     12.  NOTICES TO WARRANT HOLDERS.  Nothing contained in this Agreement shall
be construed as conferring upon the Holder or Holders the right to vote or to
consent or to receive



notice as a shareholder in respect of any meetings of shareholders for the
election of directors or any other matter, or as having any rights whatsoever
as a shareholder of the Company.  If, however, at any time prior to the
expiration of the Warrants and their exercise, any of the following
events shall occur:

          (a)  the Company shall take a record of the holders of its Common
     Stock for the purpose of entitling them to receive a dividend or
     distribution payable otherwise than in cash, or a cash dividend or
     distribution payable otherwise than out of current or retained earnings, as
     indicated by the accounting treatment of such dividend or distribution on
     the books of the Company; or

          (b)  the Company shall offer to all the holders of its Common Stock
     any additional Common Stock or other shares of capital stock of the Company
     or securities convertible into or exchangeable for Common Stock or other
     shares of capital stock of the Company, or any option, right or warrant to
     subscribe therefor; or

          (c)  a dissolution, liquidation or winding up of the Company (other
     than in connection with a consolidation or merger) or a sale of all or
     substantially all of its property, assets and business as an entirety shall
     be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
shareholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale.  Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be.  Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection with the declaration or
payment of any such dividend or distribution, or the issuance of any convertible
or exchangeable securities or subscription rights, options or warrants, or any
proposed dissolution, liquidation, winding up or sale.

     13.  NOTICES     All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made when
personally delivered or sent by registered or certified mail (return receipt
requested, postage prepaid), facsimile transmission or overnight courier:

          (a)  if to a registered Holder of the Warrants, to the address of such
     Holder as shown on the books of the Company; or

          (b)  if to the Company, to the address set forth in Article 1 of this
     Agreement or to such other address as the Company may designate by notice
     to the Holders.
