When Microsoft Corp. announced last week that it was introducing a  "virtual wallet" based on the Secure Electronic Transactions protocol, many   in the electronic commerce world cheered.   
SET, designed to secure card-based purchases over the Internet, has been  viewed as a key to the future development of on-line commerce. 
  
MasterCard and Visa came to an agreement last year on SET, but actual  implementation has been slow. 
International Business Machines Corp. and MasterCard are testing an SET-  compliant Internet commerce system in Europe, but a true end-to-end   transaction-through links among consumers, merchants, and banks-has yet to   take place in the United States.     
  
With Microsoft's unveiling of its Wallet software, and with its related  announcement of an alliance with Hewlett-Packard Co. and Verifone Inc. to   provide a complete SET software package, industry analysts and even some of   Microsoft's E-commerce rivals were heartened.     
"With SET development so far, there has been one critical missing piece,  and that was the consumer," said Victor Wheatman, an analyst with the   Gartner Group in San Francisco. "With the involvement of Microsoft and the   likelihood of trials with major banks this summer, it appears SET is   starting to overcome the technological hurdles."       
Mr. Wheatman said bankers will find that Microsoft's SET efforts will  not run counter to their interests. 
  
"Microsoft has been put up as the bogeyman, but I'm not sure they really  want to get into banks' space," he said, adding that Microsoft's reputation   for reliable and easy-to-use technology can help make SET-based payment   systems more palatable to consumers.     
"Banks, while they like to think they own the customer, have not  necessarily shown the greatest acumen in their technology approaches to   consumers," Mr. Wheatman said.   
Jonathan Weinstein, group product manager for Internet commerce at  Microsoft, agreed with Mr. Wheatman's assessment of Microsoft's intentions.   "In terms of the electronic commerce standards we are trying to support,   including SET, we want financial institutions to provide guidance," he   said. "We don't want to tell financial institutions what to do-it's a   collaborative effort."         
He added that while banks and the card associations hope SET will reduce  the opportunity for fraud and thus stimulate Internet transactions,   Microsoft sees it as just another way to get more people to use personal   computers.     
  
Mr. Weinstein said the Microsoft Wallet, which Windows-based PC users  can use to select various payment methods and shipping addresses for goods   purchased over the Web, can assist banks in convincing consumers that with   SET, the Internet is safe for shopping.     
"The value the Wallet adds is what we're very good at, which is making  software that is easy to understand and gives a pleasant user experience,"   Mr. Weinstein said.   
Mr. Weinstein noted that the Wallet will allow banks to include payment  mechanisms under their own brand names, which should assuage yet another of   bankers' fears that their cyber-identities will be overshadowed by   Microsoft's.     
Even Cybercash Inc. of Reston, Va., a pioneer in developing a virtual  wallet, was among 10 Internet payment-technology companies that have agreed   to support Microsoft's strategy.   
"We endorse and support the Microsoft Wallet because we are a provider  of services to financial institutions and merchants that helps them   facilitate Internet payments, whether the consumer is using a Cybercash   wallet or a Microsoft wallet," said Richard Crone, vice president of   Cybercash.       
"To us, it's a great vote of confidence for the architecture that we've  designed."
