The sudden growth of the Internet, and especially the World Wide Web, in the mid-1990s created a demand for secure online financial transaction applications. Verifone has taken the lead in designing applications conforming to the Secure Electronic Transaction (SET) standards developed by Visa Inc. and MasterCard. With the $28 million 1995 acquisition of Enterprise Integration Technologies, the company that developed the Secure HyperText Transfer Protocol (S-HTTP), and a $4 million equity investment in CyberCash, Inc., led by Verifone founder William Melton, and with 1996 partnership agreements with Internet browser leaders Netscape, Oracle Corporation, and Microsoft, Verifone has rolled out a suite of software products targeted at consumers, merchants, and financial institutions allowing secure purchases and other transactions online. Purchases over the Internet, which still produced as little as $10 million in 1995, are expected to reach into the billions by the turn of the century. Verifone has also been working to marry the smart card to the Internet; in 1996, the company introduced the Personal ATM (P-ATM), a small smart card reader designed to be attached to the consumer's home computer, which will enable the consumer not only to make purchases over the Internet, but also to "recharge" the value on the card. Verifone has also partnered with Key Tronic to incorporate a P-ATM interface directly into that company's computer keyboards.
