Now, RFID CARD many companies put towards a Sim integrated NFC technology, the NFC chip baked into the SIM card, in an attempt to acquire a SIM - the merge of NFC. To integrate the mobile payment on the Sim, you don't must change phone, greatly save the fee, and inherited the past some standard, for operators, the project startup faster, their charges are also reduced.
