Google Wallet hasn't had an easy start. Despite becoming the de facto standard for payment in the Android Market/Google Play Store, its adoption with consumers and retailers for NFC-based payments is effectively nil, with CitiBank and Mastercard being the only non-carrier infrastructure partners of note. The fact that the service has suffered multiple privacy scares and a short feature outage doesn't help. So it's no surprise when Bloomberg reports that Google's top brass is reevaluating their strategy, with the possibility of adding a revenue share system for the carriers that support it.
In the midst of the recent flurry of Google Wallet news, Isis has announced that they will release an Android application when the payment system is released next year. While this announcement would be more significant if the application were released today, it still gives the application a fighting chance against recently launched Google Wallet.
