Corroborating some pretty hard evidence of the physical Google Wallet card's existence we revealed last week, TechCrunch noticed this morning that a definite reference to that card has appeared on Wallet's official support site. More importantly, though, this confirms my own suspicions about the future of the Google Wallet app in light of the physical card: near-universal compatibility.
According to the support page, the new non-NFC version of the Wallet app will be compatible with any Android 2.3.3+ device, which is pretty much the vast majority of Android devices out there. This is big. This is the "circumvention" of the carriers we heard rumblings of earlier this year.
