Google Wallet still has limited usefulness. NFC payments are still only supported on a tiny fraction of Android users, using a custom build of the wallet app not available in the Google play store. Only some phone distributors are given access to this custom build. My phone has android 4.4, NFC support, and Google wallet installed, but I can't do NFC payments. How do they expect to compete like that?
Google Wallet (installed from the standard Play Store) on my T-Mobile US HTC One (both M7 and new M8) works great paying for purchases anywhere they accept NFC payments (including Apple Pay locations). I previously used it at CVS before they turned off their NFC terminals, I use it at Panera, McDonalds, Kroger, Best Buy, Target. You're making claims that are not based in fact.
