Google has announced that it is pushing a software update to retail Nexus 7 devices that will bring Google Wallet to the tablet. This appears to be the same 4.1.1 OTA that I/O devices received last week. El Goog says it is pushing the update now and that users should receive it shortly. I received it on my retail Nexus 7 just a few minutes ago.
If for some reason you are unfamiliar with Google Wallet, it is an app that uses NFC to allow you to pay for items on the go.
