                         RE:   Registration Statement on Form S-1



Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-1 filed under Rule
462(b) of the Securities Act of 1993, as amended (the "1933 Act"), by Infinity
Financial Technology, Inc., a Delaware corporation (the "Company"), with the
Securities and Exchange Commission on October 25, 1996 (the "Registration
Statement"), relating to the registration under the 1933 Act, of up to 218,500
shares of the Company's common stock, $0.001 par value (the "Stock") (including
28,500 shares subject to the underwriters' over-allotment option) which are to
be offered and sold by certain selling stockholders (the "Selling
Stockholders"). We understand that the Stock is to be sold to the underwriters
named in the Registration Statement for resale to the public. As counsel to the
Company, we have examined the proceedings taken, and are familiar with the
proceedings proposed to be taken, in connection with the issuance and sale by
the Selling Stockholders of the Stock.

     We are of the opinion that the shares of Stock to be offered and sold by
the Selling Stockholders have been duly authorized and legally issued and are
fully paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us in the Registration
Statement, the prospectus constituting a part thereof and any amendments
thereto.


                                     Very truly yours,


                                   /s/ Morrison & Foerster LLP
