Secure Element SIM - ISIS Mobile Payments, maybe Google Wallet?

view story

http://forum.xda-developers.com – The Isis Mobile Wallet was announced yesterday in limited rollout to Austin and Salt Lake City for now. http://news.paywithisis.com/ What struck me as interesting is the reference to needing to got to an AT&T store and pick up a new "secure element SIM". Since I don't live in one of those cities, I'm wondering where I can find more details about this SIM and if it's something that can be used to finally bring Google Wallet support to our phones.
