Updated 1/28/2019: Softcard (formerly known as ISIS) has been discontinued. The service is no longer available for download, and it will not receive any ongoing support.
Formerly known as Isis, Softcard (gosoftcard.com) is a digital wallet app from AT&T, T-Mobile, and Verizon that is available for free to smartphone users who utilize one of these three wireless carriers. Like its competitor Google Wallet, Softcard allows users to store their credit and debit card information in their phones and make payments using “tap and pay” functionality through NFC technology.
Since iPhones do not currently include NFC capability, Softcard users on iPhones will need to acquire an accessory case containing an NFC antenna in order to use the service. Softcard also allows users to store and access loyalty programs. First Data provides the processing network for Softcard payments, but users will not directly interact with First Data at any point when using the service.
