In the beginning there was Android Pay. Then Google Wallet appeared. A physical Google Wallet card was available. Google Pay was a separate app. Google Wallet and Android pay were discontinued and folded into Google Pay. Now Google Wallet will be coming back and this time it’s pretty much like a real wallet. Prepare for Google Pay to go away for 7 years or so.
Saving membership info, driver’s licenses, passes, and incorporating Google Pay means you can leave your wallet behind and lose access to it all when you run out of battery.
State driver’s licenses are coming, that’s on the states. Google Wallet is coming, that’s on Google.
