Peer-to-peer mode: Put two NFC-enabled devices close together to achieve peer-to-peer data transmission;
Card simulation mode: simulate a device with NFC function into a contactless card, such as bus card, bank card;
Card reader mode: the NFC phone is used as a card reader, which can read the data on the contactless card. For example, use the recharge app to recharge physical and virtual transportation cards, and query the balance of transportation cards.
Note:
1. realme phones that support NFC all support the above three modes.
2. The NFC bus card can be used without network and power (it can only be used when the phone is powered off automatically, and the user cannot actively shut down).
