What Are Passive RFID Tags?

Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, readers, communicators, and readers (depending on whether the electronic tag can wirelessly rewrite data). The electronic tag and the reader realize the spatial (non-contact) coupling of the RF signal through a coupling element; in the coupling channel, according to the timing relationship, the energy transfer and data exchange are realized.

Data storage: Compared with the traditional form of tags, the capacity is larger (1bit-1024bit), and the data can be updated at any time, and can be read and written.

Reading and writing speed: and

In 1937, the US Naval Research Laboratory (NRL) developed

RFID radio frequency identification is a non-contact type

The basic working principle of RFID technology is not complicated: tag entry

The problem of China's electronic label standards has always been the focus of attention at home and abroad, and it is also a core issue about whether it can promote the rapid development of China's RFID industry as soon as possible. It was learned at the working meeting of the Electronic Label Standards Working Group held in Beijing on June 26, 2006: After joint efforts in 2007, China's Electronic Label Group has proposed 13.56MHz

As a data carrier, electronic tags can perform identification, item tracking,

China's electronic label market is in its infancy, and various regions have begun to apply electronic label-based applications, mainly used in

Open source software radio technology has a profound impact on the radio industry, and electronic labels are no exception. GNU Radio is a free software development tool suite. It provides signal operation and processing modules that can be used to implement software-defined radios on easy-to-manufacture, low-cost radio frequency (RF) hardware and general-purpose microprocessors. This kit is widely used by amateurs, academic institutions and commercial institutions to research and build wireless communication systems. GNU Radio applications are mainly written in the Python programming language. But its core signal processing module is C ++ built on a microprocessor with floating point arithmetic. Therefore, developers can simply and quickly build a real-time, high-capacity wireless communication system. Although its main function is not an emulator, GNU Radio supports the study of algorithms for signal processing of pre-stored and (signal generator) generated data without RF RF hardware components.
