NFC development and application scheme

NFC is a very unique technology and a very important technology, at least it will become a breakthrough direction for smart wear and smart home.

Most people's cognition of NFC should come from science fiction movies, but few people knew the specific name of this technology at that time. Just like other smart wearable technologies, we have realized that people can use some intelligent wearable devices to expand some functions of people with the help of science fiction films, but we always feel that this is a bit far away from us until Google released smart glasses. Only then did we realize that the scenes of sci-fi movies are already around us, and they are no longer out of reach, but within reach.

NFC: Near Field Communication (near field wireless communication)

Based on RFID technology at 13.56MHz

Operating mode:

The main working mode of NFC terminal is similar to that between lovers, nothing more than active, passive and two-way. To put it simply, there are three modes: men chasing women, women chasing men, and mutual love:

1. Active: In active mode, the NFC terminal can be understood as a card reader, which actively sends out radio frequency fields to identify and read/write other NFC device information.

2. Passive: This mode is just the opposite of the active mode. At this time, the NFC terminal can be understood as a card instead of a card reader. It only responds passively in the radio frequency field sent by other NFC devices and is read/written. information.

3. Two-way mode: In this mode, both NFC terminals actively send out radio frequency fields to establish point-to-point communication, which means that both NFC devices are in active mode. A simple understanding is that an NFC terminal not only has the function of reading and writing, but also has the function of being read and written.

Consumer Electronics: Bluetooth headset/speaker, smart router, mobile power supply, Bluetooth keyboard and mouse, NFC keyboard, game controller, universal remote control.

Wearable products: rings, necklaces, earrings, watches.

Medical electronics: blood glucose meter, pedometer

Anti-counterfeiting management: alcohol anti-counterfeiting, assets, asset management

Others: third-party payment POS, smart home, poster advertisement, electronic price tag, game doll, printer, camera.

NFC tags can be ubiquitous, and reading and writing devices (mainly mobile phones) and system applications are the key.
