Rule 13a-14a  Certification (Chief Financial Officer)               Exhibit 31.2
-----------------------------------------------------

I, William L. McMahon, certify that:

     1.   I have  reviewed  this  annual  report on Form 10-K of Global  Payment
          Technologies, Inc. ("GPT");

     2.   Based on my knowledge,  this annual 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 annual report;

     3.  Based on my knowledge, the financial statements, and other financial
         information included in this annual 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 annual report;

     4.  GPT's other certifying officer and I are responsible for establishing
         and maintaining disclosure controls and procedures (as defined in
         Exchange Act Rules 13a-14 and 15d-14) for GPT and have:

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

         b)   evaluated the effectiveness of GPT's disclosure controls and
              procedures and presented in this annual report our conclusions
              about the effectiveness of the disclosure controls and procedures
              as of the end of the period covered by this annual report based
              upon 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;

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

          a)   all  significant  deficiencies  and  material  weaknesses  in the
               design or operation of internal controls over financial reporting
               which are reasonably  likely to adversely affect GPT'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 GPT's  internal
               controls over financial reporting; and
