In the UK one of the banks (Barclays) has setup a mobile app PingIt for this same concept. Someone sent me money with it, had to sign up to receive it. Due to what I imagine is UK banking laws, a large amount of id/proof of address was required to fully register my account, so that I could also send money. To verify my address they send a snail mail letter out with a verification code, being a student away at university (moving house every 12 months), I used my parents address. 3 weeks later when I was back home I attempted to verify my address, only to find the code had expired (despite it never mentioning anywhere that it must be done within x days). After rejecting the code, the app appeared to wipe all data regarding my account, now asking me to sign up from the beginning again. This experience has really ruined my hopes, for a system I was already reluctant to enter.
