mobile payments are concerned, there is no problem to be solved
Really? No problem to be solved? Wonder if they’ve ever been to a restaurant with a bunch of friends splitting the bill. That’s one of a zillion of places mobile payments would be damn helpful. I don’t think it’s necessarily NFC or other hardware solutions that will be the answer but it will definitely come, no doubt at all.
Credit cards are ubiquitous
Yes and so was cash, before we had credit cards. That doesn’t mean something new can become ubiquitous too, does it? But even then, some places in the world even in the most developed countries it’s really hard to live cashless, so question is when we can live with our mobiles as wallet 100%?
