NFC
Introduction to NFC
Near Field Communication (NFC) is a technology that enables short-distance wireless communication.
Through NFC's contactless communication, two devices can transfer data in real time when they are
within 10 cm (4 inches) of each other. In addition to data transfer, NFC also allows you to make
payments.
NFC can be used in multiple scenarios with different requirements and methods.
Point-to-point mode: Transfers data between two NFC-enabled devices within a short distance. No
pairing is required and a more secure connection is established.
Scenarios
l Transfer les (such as images, apps, and contacts).
l Quickly establish a connection between devices (like Bluetooth pairing or hotspot sharing).
Limitations
l Both devices need to support NFC.
l During data transmission, devices must be within 10 cm (4 inches) of each other.
l Screen must be on and unlocked when using NFC.
Read/Write mode: Supports reading and writing NFC tags.
