Which Three Communication Modes Can NFC Work
Sep 17, 2018

NFC is another wireless way. Close-range technology works only when two Panel PCs are in close proximity to one another, so eavesdropping is almost impossible. In addition, NFC is unique in that how it uses energy. In the two Panel PCs, only one of the Panel PCs needs to be powered, that is, the interaction between the two parties can be realized. The first device that receives power can power the second device, so the second device can save power for other uses or no battery at all.

NFC is a dedicated subset of radio frequency identification (RFID). It operates at 13.56MHz and performs many of the same functions as RFID tags and contactless smart cards. NFC works in one of three communication modes: read/write, point-to-point, and card emulation.

Read/write mode 

In the read/write mode, the NFC reader reads the data in the NFC smart object and performs the corresponding operation based on the relevant information. For example, with an NFC-enabled mobile phone, users can automatically connect to the website via the retrieved URL, send SMS (SMS) text, get coupons, etc. without typing in the text, all just by making the device and object do a light touch can be done.

Peer to peer 

In point-to-point mode, any NFC-enabled reader can communicate with another NFC reader to exchange data, and is as secure, intuitive, and simple as the read/write mode. In this mode, one of the readers is used as a tag to create a communication link. For example, two Panel PCs with readers, can communicate with each other.

Card emulation mode 

NFC Panel PCs in card emulation mode can replace contactless smart cards, allowing NFC Panel PCs to be used on existing contactless card infrastructure to perform operations such as ticketing, access control, transit, toll stations, and contactless payments.
