 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).
