The model is with functions of NFC device simulation into a contactless card, such as entrance card, bank CARDS, etc. Card simulation mode is mainly used to store, transport and other non-contact mobile payment applications, the user as long as the phone near the card reader, and enter the password to confirm or receiving transactions can be directly. This way, the card power supply through non-contact card reader RF domain, even the NFC device also can work without power.

In the application mode, NFC read equipment from NFC mobile phones have the ability to TAG data, and then the data sent to the application processing system for processing, as shown in figure 1. Based on the typical application of the model include the local payment, access control, electronic ticket applications and so on.

After andriod4.4, can support the HCE (host card emulation), through the mobile phone software simulation card implementation model, not only controlled by the SE card mode as before.
