5G is a new generation of broadband mobile communication technology with high speed, low latency and large connection characteristics.

The communication standards of radio frequency tags are the basis for tag chip design. The current international communication standards related to RFID mainly include ISO/IEC 18000 standard, ISO11784/ISO11785 standard protocol, ISO/IEC 14443 standard, ISO/IEC 15693 standard, EPC standard, etc.

The working principle of fingerprint recognition mainly includes three functions: reading of fingerprint images, extracting features, and comparing fingerprints. Common fingerprint recognition technologies are: optical, capacitive, and ultrasonic.

According to the regulations of various countries/regions, UHF RFID frequencies are different. From the common UHF RFID frequency bands around the world, the North American frequency band is 902-928MHz, the European frequency band is mainly concentrated in 865-858MHz, and the African frequency band is mainly concentrated in 865-868MHz, the highest frequency band in Japan is 952-954MHz, and the frequency band in South Korea is 910-914MHz. There are two frequency bands in China, Brazil, and South Africa. The frequency bands in China are 920-925MHz and 840-845MHz, and the frequency bands in Brazil are 902-907.5MHz and 915-928MHz. On the whole, the UHF frequency bands in the world are mainly concentrated in 902- 928MHz and within 865-868MHz.

Supply chain management refers to the management and coordination of the entire process from the procurement of raw materials to the delivery of final products to customers. The Internet of Things technology is to exchange data through physical equipment networks, sensors, software and other tools, connect objects and equipment, and realize intelligent interaction and real-time monitoring of information. IoT technology can be well applied in supply chain management to improve the visibility, efficiency and traceability of supply chain processes.

Thingmagic M6e-Micro, adopts ultra-small module structure design, and excellent "fast search algorithm", especially for fast-moving label reading,which can be embedded in a variety of commonly used handheld and portable devices.

The passive electronic price tag is a new type of commodity label based on RFID technology. Compared with the traditional paper price tag, it has higher flexibility and readability, and it has become popular in retail scenes such as shopping malls and supermarkets.

In recent years, RFID technology and products have been widely used in various industries. What is the manufacturing process of RFID chips?

AEI is an electronic identification system used by the North American railroad industry. Composed of rfid electronic tags and rfid readers installed on both sides of the vehicle, AEI uses RF technology to identify railway equipment.

The Internet of Things - Real-time acquisition of massive agricultural data lays the foundation for agricultural digitalization. The Agricultural Internet of Things is an important application field of the Internet of Things and the main source of data in digital agriculture.

The RFID antenna is a crucial part to realize the reading function of the RFID hardware device. The difference of the antenna directly affects the reading distance, range, etc., and the antenna is an important factor affecting the reading rate. The antenna of the RFID reader can be mainly devided into linear polarization and circular polarization according to the energy mode.

The read and write distance of a radio frequency identification (RFID) reader depends on many factors, the antenna gain is one of important factors that affect the reading and writing distance of the RFID reader

RFID electronic tags are now widely used in warehouse management, logistics tracking, food traceability, asset management and other fields. At present, the widely used UHF RFID tag chips on the market are divided into two categories: imported and domestic,include Mainly IMPINJ, ALIEN, NXP, Kiloway, etc.

The communication interface is particularly important for the docking of information and products. The interface types of RFID readers are mainly divided into wired interfaces and wireless interfaces, which can be further subdivided into different types

Each frequency band tag has a corresponding protocol，the ultra-high frequency (UHF) has two protocol standards to choose. One is ISO18000-6B, and the other is the EPC C1G2 standard that has been accepted by ISO as ISO18000-6C.

Mini drones combines with RFID (radio frequency identification) technology can achieve RFID collection of information in harsh environments and improve the intelligence of UAVs, also can reduce costs and strengthen supply chain management.
