REDMOND, Wash. (AP) -- Microsoft Corp. on Tuesday launched its ``MSN Wallet'' service, a new version of its online identity program designed to let consumers make purchases at Internet sites more easily.

Under the program, users add their credit card information, billing address and other personal information to MSN Wallet's database. Then, they can have their information automatically entered for them while shopping at Web sites that are part of the MSN Wallet network.

Participating retailers include Nordstrom, OfficeMax, Blue Nile and Ritz Camera.

The program replaces the Passport Express Purchase program, which will end in March 2003. Customers with Passport Express Purchase will need to reapply for the new MSN Wallet program.
