Comment It already exists (Score 1) 137
It already exists, in France in Nice. Project was launched last summer in production.
It requires both SIM card and mobile compliant with NFC technology (Near Field Communication).
But it's the very beginning, mobile constructors don't provide any list of devices compliant yet.
You need to be very close to the terminal to have the transaction initiate, no way you can have it done from your pocket.
And everything can be locked by your operator in no time OTA (over the air) if you loose your phone.
For the moment, this service is provided by your bank, it's not available in the services of your mobile operator ... yet.
