  1.
    
    I have reviewed this Form 10-QSB of US Wireless Data, Inc.;2.
    
    Based on my knowledge, this 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 small business issuer as of, and for, the periods present in
this report;4.
    
    The small business issuers other certifying officer(s) 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))
and internal control over financial reporting (as defined in Exchange
Act Rules 13a-15(f) and 15d-15(f)) for the small business issuer 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 small business issuer,
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; and(b)
    
    Designed such internal control
over financial reporting, or
caused such internal control over
financial reporting to be designed
under our supervision, to provide
reasonable assurance regarding the
reliability of financial reporting
and the preparation of financial
statements for external purposes
in accordance with generally
accepted accounting principles;
and(c)
    
    Evaluated the effectiveness of the
small business issuer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(d)
    
    Disclosed in this report any
change in the small business
issuers internal control over
financing reporting that occurred
during the small business issuers
most recent fiscal quarter (the
small business issuers fourth
fiscal quarter in the case of an
annual report) that has materially
affected, or is reasonably likely
to materially affect, the small
business issuers internal control
over financial reporting; and
 5.
    
    The small business issuers other certifying officer(s) and I have
disclosed, based on our most recent evaluation of internal control
over financial reporting, to the small business issuers auditors and
the audit committee of the small business issuers board of directors
(or persons performing the equivalent functions):
 (a)
    
    All significant deficiencies and
material weaknesses in the design
or operation of internal control
over financial reporting which are
reasonably likely to adversely
affect the small business issuers
ability to record, process,
summarize and report financial
information; and(b)
    
    Any fraud, whether or not
material, that involved management
or other employees who have a
significant role in the small
business issuers internal control
over financial reporting.
