Personally, given how lax most people are with their phones - even those who are otherwise top notch with their electronics security - the idea of phones being able to tap and pay scares me on some level.
I had always been under the impression that debit cards didn't have anywhere near the same theft/fraud protections as CC's did. The notion being that as long as you protect your PIN, the debit card is worthless, so any fraud charges are in some way your own fault. Whereas a stolen CC can still be used online and in a lot of places where the counterclerk can't be bothered to check for ID (i.e. quite a bit of the USA, even now).
