Section 302 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  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
