 I,
          Dean
          A. Stewart, Chief Financial Officer certify that:
 
 1.
          I have
          reviewed this quarterly report on Form 10-Q of BMX Development Corp. (FKA
          Biometrix International, Inc.)
 
 2.
          Based
          on my knowledge, the 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 quarterly report;
 
 3.
          Based
          on my knowledge, the consolidated financial statements, and other consolidated
          financial information included in this quarterly report, fairly present
          in all
          material respects the consolidated financial condition, consolidated results
          of
          operations and cash flows of the registrant as of, and for, the periods
          presented in this quarterly report;
 
 4.
          The
          registrant's other certifying officers and I am responsible for establishing
          and
          maintaining disclosure controls and procedures (as defined in Exchange
          Act Rules
          13a-15(c) and 15d-(e)) for the registrant 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 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 period
          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, to the registrant's auditors and the audit committee
          of the
          registrant's board of directors (or persons performing the equivalent
          functions):
 
 a)
          all
          significant deficiencies in the design or operation of internal controls
          which
          could adversely affect the registrant's ability to record, process, summarize
          and report financial data and have identified for the registrant's auditors
          any
          material weaknesses in internal controls (all of which do not apply);
          and
 
 b)
          any
          fraud, whether or not material, that involves management or other employees
          who
          have a significant role in the registrant's internal controls, (all of
          which do
          not apply).
