Following its mammoth I/O keynote yesterday, which saw a number of services updated and new ones introduced, Google has added support for a number of additional devices — including the latest flagships from Samsung and HTC — to its Google Wallet app for Android.

Google unveiled a shed-load of astonishing new features at the Google I/O keynote on Wednesday, some of which were more exciting than others. One of the company’s smaller — but still important — announcements was the ability to send money via a linked bank account through Gmail and Google Wallet.

BARCELONA, MOBILE WORLD CONGRESS — During a Samsung developer conference here at Mobile World Congress this morning, the Korean company unveiled a new service called Samsung Wallet, which lets Samsung smartphone owners turn tickets, coupons, membership cards, boarding passes, and more into digital cards that they can store in a virtual wallet.

The service probably sounds familiar, and it is — Samsung Wallet is basically Apple’s Passbook, but for Samsung phones. It works in almost exactly the same way, and looks very similar, too.

PassWallet, an app that allows Android devices to use passes created for Apple’s Passbook service, has been updated to add supper for NFC. Users can now “beam and redeem” all kinds of passes if they have a supported handset, something Apple’s iOS devices — which don’t support NFC — cannot do.

Last week we reported about the possibility of a physical Google Wallet card and its implications. Today, more evidence has surfaced, and this time, straight from the official Google Wallet support page. Eagle eyes spotted references to the card as well as compatible Android devices. These references have since been taken down, however, you can see it in its entirety in the screenshot above.
