Since reading this thread a week ago,I am having issues with Wallet also. The Tap &Pay feature is ready but when I go to use it it doesn't complete the checkout process, it shows (entry not allowed). I contacted Google and they said that the new update requires the phone to have version 4.4 or higher. Well I did somemore digging aroung and the Evo 4g Lte from Sprint is suppose to have a chip that reguires only 2.3 or higher. I called Google again an ask about this info I had and they said that Sprint most likely deactivated the chip so to make coustomers with older phones upgrade to a newer phone. I called Sprint about it and talked to a tech and they said that the phone should still be able to work with Wallet and said it has to be a Google problem,well go figure. Sprint did say that there is an update coming to this phone and maybe that will resolve this problem so I'm waiting.
