The China gov is working with banks and its social services orgs to integrate all accounts on a "smart card" that is an NFC connected to your phone SIM. This works as both a stored value card for things like subway entrance as well as purchases made for health services by deducting from your health care account, etc.. The roll out is happening now. I'm not sure when all 260 million cards are scheduled to be out, but a 15 million card rollout is happening in the next few months.

I am working with one of the companies supplying the cards. They and their banking partners are highly interested in value added services (better payment systems, etc) to latch on to this train thats about to leave the station. Feel free to contact me if you have any ideas ;)
