Eric, there is no reason why Samsung needs to compete with Apple on this. It would be better if they just advertised that their phones, the ones with NFC, work with Google Wallet.
Even Apple, with all their marketshare and mind share, in the USA, is taking a few months to get the credit cards they need (Discover, stupidly, is not yet on board), and the majority of banks, though it seems as though 90% of all cards issued are now compatible. Apple has close to 43% of smartphone marketshare here, while Samsung has 29%. But at least half of Samsung's consists of cheaper smartphones without an NFC chip. This would make Samsung's going it alone a very difficult proposition under the best of circumstances. If they don't use NFC, then their system would be much more complex to use, and essentially, worthless.
Samsung, with far fewer eligible phones, will have an major uphill battle in this. If they wait another year, the battle will be lost before it begins.
And then there is that terrible fingerprint scanner they have. If the phones rely on that, it's dead in the water. Surely, you've been reading about the difficulty using that? Can you imagine customers on line, nervously swiping their finger to no avail? Hopefully, next year, Samsung will have a better scanner, one that works 100% of the time, as Apple's does. It would be better yet if it worked with one hand, as Apple's does, rather than two,
