The folks over at Business Insider spotted a change on the Google Wallet website today indicating that a new version of the payment system -- separate from the recently released web version -- is "coming soon." Folks itching to get in on the fresh NFC payment action can ask for an invite right now, but alas, details about the forthcoming update are scarce. We do know that upon submitting a request for the new Wallet, users are asked if they use an Android, iOS, or "other" mobile device. So, might we be in for more widespread Wallet adoption with this next iteration? Only one way to find out, so head on down to the source, sign up, and see for yourself.
