Feature to be removed from device not running Android 4.4 or higher on April 14, 2014
Google Wallet's tap and pay feature is soon to become a KitKat only affair. According to a message sent out to users with the feature enabled, but running a lower version of Android, the new, different technology used means older versions will not be able to support it, and support for the old method is being dropped.
With KitKat, Google changed from using a secure element — a combination of hardware and firmware in your phone to keep tap and pay payments secure — to a host-based card emulation system. This allows the Wallet app and the CPU on your phone or tablet to provide security through software instead of using a hardware component. HCE services are methods that only KitKat can support, and the old secure element method is no longer supported, so the feature is now KitKat (or higher) only.
We know that few people actually use Google Wallet's tap and pay feature, but chances are this will affect more than a few of us. We're the early adopters who enjoy features like tap and pay. Hopefully, the last few current flagships still on JellyBean (Hi LG! Hi Sony!) will get updated soon.
