Android Pay officially went live yesterday. It will eventually be available and start pushing out to Google devices, but that will happen in batches. Luckily, our friends at Phandroid posted a download for the APK, so you can get it now if you want: Mediafire
In case you missed the info on Android Pay previously, it is basically the new replacement mobile payment system for Google Wallet. It's a way for Google to consolidate under the Android brand and bring new functionality to the system. Sound off and let everyone know what you think of it!
