U.S. WIRELESS DATA, INC.

               UNAUDITED PRO FORMA CONDENSED FINANCIAL INFORMATION


The following Unaudited Pro Forma Condensed Financial Statements give effect to
the purchase of certain net assets of Cellgate Technologies LLC ("Cellgate") by
U.S. Wireless Data, Inc. ("USWD"). These pro forma condensed financial
statements are presented for illustrative purposes only. The pro forma
adjustments are based upon available information and certain assumptions that
management believes are reasonable.

The Unaudited Pro Forma Condensed Financial Information is prepared using the
purchase method of accounting. For the purpose of the Unaudited Pro Forma
Condensed Financial Information presented below, the purchase price has been
calculated based upon the price of $3.50 per share of USWD Common Stock.

Under the purchase method of accounting, tangible and identifiable intangible
assets acquired and liabilities assumed are recorded at their estimated fair
values. The excess of the purchase price, including estimated direct fees and
expenses related to the merger, over the net assets acquired represents
goodwill, and is classified as other assets, on the accompanying unaudited pro
forma balance sheet. The estimated fair values and useful lives of assets
acquired and liabilities assumed are based on an independent valuation.

The Pro Forma Condensed Balance Sheet of USWD as at September 30, 2000 reflects
the financial position of USWD after giving effect to the purchase of assets and
assumption of certain liabilities of Cellgate and assumes the acquisition took
place on September 30, 2000. The Pro Forma Condensed Statement of Operations for
the fiscal year ended June 30, 2000 and the three months ended September 30,
2000 assumes the purchase occurred on July 1, 1999.

The Unaudited Pro Forma Condensed Financial Information is provided for
illustrative purposes only and does not purport to represent what the actual
results of operations or financial position of USWD would have been had the
merger occurred on the date assumed, nor is it necessarily indicative of future
results of operation or financial position.

The pro forma assumptions and adjustments are described in the accompany notes
presented on the following pages. The Unaudited Pro Forma Condensed Financial
Information should be read in conjunction with the audited financial statements
of USWD in the USWD Annual Report on Form 10-KSB for the year ended June 30,
2000, and with the unaudited financial statements of USWD in the Quarterly
Report on Form 10-QSB for the period ended September 30, 2000 and the audited
financial statements of Cellgate for the year ended December 31, 1999 and the
unaudited financial statements of Cellgate for September 30, 2000 included
herein.
