What is an NFC chip?
What is NFC? NFC is actually a short-range wireless communication technology, so what about NFC function? There are many built-in NFC chips in mobile phones. NFC is the abbreviation of Near Field CommunicaTIon, which is short-range wireless communication technology. NFC is a contactless identification and interconnect technology that enables close-range wireless communication between mobile devices, consumer electronics, PCs, and smart control tools.
NFC chip function
The NFC chip is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission (within ten centimeters) to exchange data between electronic devices. This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID. It was first developed by Sony and Philips, and is mainly used to provide M2M (Machine to Machine) communication in handheld devices such as mobile phones. NFC provides a simple, touch-enabled solution that allows consumers to easily and intuitively exchange information and access content and services.
NFC chip
The NFC chip has mutual communication functions and computing power. It also contains encryption logic in the Felica standard. The MIFARE later standard also adds an encryption/decryption module (SAM). In order to promote the development and popularization of NFC, the industry has created a non-profit standard organization, the NFC Forum, to promote the implementation and standardization of NFC technology and ensure the cooperation between equipment and services. Because near-field communication has natural security, NFC technology is considered to have great application prospects in the field of mobile payment.
NFC application
The NFC device can be used as a contactless smart card, a reader terminal for a smart card, and a device-to-device data transmission link. Its wide range of applications, NFC applications can be divided into four basic types:
Contact and finish. For applications such as access control or traffic/activity check-in, the user simply places the device with the ticket or access code in proximity to the reader. It can also be used for simple data capture applications, such as reading a URL from a smart tag on a poster.

Contact, confirmation. For applications such as mobile payments, the user must enter a password to confirm the transaction or only accept the transaction.
Contact, connection. By connecting two NFC-enabled devices, you can perform point-to-point network data transmission, such as downloading music, exchanging images, or synchronizing address books.
Contact and explore. NFC devices may provide more than one function, and consumers can explore the capabilities of the device and identify potential features and services of the NFC device.
