Sprint is the only carrier that has so far offered a handset with Google Wallet pre-loaded. Verizon blocked the service from appearing on its version of the Samsung GALAXY Nexus. Now, Google is said to be working on Google Wallet 2.0 which will rely more on the cloud to pass along payments, promotions and offers. Google's acquisition of payment technologies company TxVia a few months ago was done to help Google Wallet improve its performance and gain more traction among carriers. TxVia specialties are gift and pre-paid cards which might reveal some of what the Mountain View based company has in mind. Whatever changes to Google Wallet will be announced at Google I/O later this month could all be moot unless Google gets carriers to sign up for its service. And now that Sprint is apparently working on "Touch," the one carrier that has supported Google Wallet could soon replace it with its own platform.
A Sprint source says that its "Touch" will be a legitimate challenger to ISIS, which is expected to launch in two cities this summer. The mobile operator was originally a member of the group that developed ISIS until it dropped out in 2010. Unlike the service to be offered by its three main competitors, Sprint will make "Touch" an open system with APIs made available to developers to use in apps. Additionally, ISIS will require the use of a SIM card for security while Sprint's platform will use an embedded chip. This is because Sprint is not as far along with the development of its LTE network to use a SIM card as a security element. T-Mobile, of course, is a GSM carrier as is AT&T and already has SIM cards in use.
