What is NFC tag
NFC tag ( Near Field Communication Tag), i.e., near field communication tag, is an electronic tag based on near field communication technology. Usually consists of radio frequency chip, antenna and tag shell. The chip is used to store data, such as text, URL, pictures and other information; the antenna is used to receive and send wireless signals; the shell plays a role in protecting the internal components.
It uses the radio frequency of 13.56MHz and works based on the principle of electromagnetic induction. When the NFC-enabled device is close to the NFC tag, the magnetic field generated by the device will provide energy for the tag, which will enable the chip in the tag to work and establish a connection through electromagnetic induction, realizing fast data transmission.
Features
1. No battery required: passive or semi-passive design, no battery power supply is required, relying on the electromagnetic induction of the reading device to obtain energy.
2. High security: the use of radio frequency identification technology, with a high degree of security, can be encrypted and decrypted data processing, to protect the data from being stolen.
3. Read and write fast: read the internal information of the label only need to be close to the label equipment, without physical contact, fast data transmission speed.
4. Low cost: with the development of technology, the cost of NFC tags is gradually reduced, suitable for mass production and application.
Application Scenarios
1. Mobile payment: Users store payment information such as bank cards and electronic wallets in NFC tags, and when shopping, they only need to bring NFC-enabled cell phones and other devices close to the NFC tags of payment terminals to complete payment.
2. Access control system: The NFC tag is used as an access control card, which is pasted on the door or installed in the access control equipment, and the user can open the access control by approaching the NFC-enabled cell phone or card.
3.Smart Home: By sticking NFC tags on electrical equipment, users can store the control instructions of the equipment in the tags and touch the tags with their cell phones to realize the control of home appliances such as switching and adjusting lights.
4.Logistics and inventory management: By attaching NFC tags to the packaging of goods, the name, quantity, source and destination of the goods can be recorded, which facilitates tracking and management in the logistics process.
5. Product anti-counterfeiting and traceability: Add NFC tags to product packaging, and consumers read the tag information through mobile devices to obtain product authenticity verification and traceability information related to production and transportation.
