EXHIBIT 31.2

                                  CERTIFICATION
            Pursuant to Section 302 of the Sarbanes-Oxley Act of 2002

I, John H. Lowry, certify that:

      1.    I have reviewed this quarterly report on Form 10-Q of Catuity, Inc;

      2.    Based on my knowledge, this quarterly report does not contain any
            untrue statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the circumstances
            under which such statements were made, not misleading with respect
            to the period covered by this report;

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this report, fairly present in all material
            respects the financial condition, results of operations and cash
            flows of the registrant as of, and for, the periods presented in
            this report;

      4.    The registrant's other certifying officers and I are responsible for
            establishing and maintaining disclosure controls and procedures (as
            defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
            registrant and we have:

            a)   Designed such disclosure controls and procedures to be designed
                 under our supervision, to ensure that material information
                 relating to the registrant, including its consolidated
                 subsidiaries, is made known to us by others within those
                 entities, particularly during the period in which this report
                 is being prepared;

            b)   Evaluated the effectiveness of the registrant's disclosure
                 controls and procedures and presented in this report our
                 conclusions about the effectiveness of the disclosure controls
                 and procedures, as of the end of the period covered by this
                 report based on such evaluation; and

            c)   Disclosed in this report any change in the registrant's
                 internal control over financial reporting that occurred during
                 the registrant's most recent fiscal quarter (the registrant's
                 fourth fiscal quarter in the case of an annual report) that
                 has materially affected, or is reasonably likely to materially
                 affect, the registrant's internal control over financial
                 reporting; and

      5.    The registrant's other certifying officers and I have disclosed,
            based on our most recent evaluation of internal control over
            financial reporting, to the registrant's auditors and the audit
            committee of the registrant's board of directors (or persons
            performing the equivalent function):

            a)   All significant deficiencies or material weaknesses in the
                 design or operation of internal control over financial
                 reporting which are reasonably likely to adversely affect the
                 registrant's ability to record, process, summarize and report
                 financial information; and

            b)   Any fraud, whether or not material, that involves management
                 or other employees who have a significant role in the
                 registrant's internal control over financial reporting.
