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.

Due to the uniqueness of the chip code of RFID electronic tag, if the RFID electronic tag is embedded in the green tire during the tire building process, and then sealed in the tire sidewall after vulcanization, which can strengthen product supply chain management and brand protection, avoid the problem of counterfeiting products, can realize the traceability of tire life course.

NFC cards are mainly divided into ID cards and IC cards. ID cards are mainly being read data by NFC reading devices; IC cards have chips that specifically process card data.

NFC and RFID both support the 13.56 frequency band, but what is the difference between NFC and RFID ?

RFID electronic tags are composed of tags, rfid readers and data storage and processing systems. According to different power supply methods, RFID can be divided into three types: active RFID, semi-active RFID, and passive RFID.

NFC stands for short-range wireless communication technology, which evolved from contactless radio frequency identification (RFID), a short-range high-frequency radio technology that operates within a distance of 10 centimeters at a frequency of 13.56MHz.

The RFID personnel attendance monitoring system can uses RFID passive identification cards and applies automatic information identification technology to perform real-time attendance, tracking and positioning, and management of coal mine personnel.

RFID and barcodes are both data-carrying technologies that store product information on labels, but they are different. So how to distinguish and choose these two kinds of labels and scanning equipment?

In the practical application of RFID, it is often required to read a large number of tags at the same time, such as the inventory of warehouse goods. How to improve the multi-tag reading rate of UHF RFID equipment in this case?

The oilfield RFID inspection terminal can realize many functions such as the standardization of daily inspection, the standardization of data records, the quantitative management of operation performance, and the query of accident responsibility.

As the most basic part of passive Internet of Things technology, UHF RFID passive tags have been widely used in a large number of applications such as supermarket retail, logistics and warehousing, book archives, anti-counterfeiting traceability, etc. In practical applications, what exactly does the chip of the UHF RFID passive tag rely on to supply power?
