Scanners are common in businesses and many homes. While they used to be very expensive, they’ve become much more affordable in recent years – especially since the advent of hand-held scanners. Why have a hand-held scanner? Handheld scanners offer many advantages to those who use them, whether for business or personal purposes. Hand-held scanners are…
1. The sensitivity of the RFID reader The range limitations of RFID tags are a thing of the past. Today’s state-of-the-art tags require very little energy and can be powered over a range of more than 20 meters. To achieve these ranges, RFID readers need to be able to pick up even weak signals from farther…
Radio frequency identification technology is a non-contact automatic identification technology. Its basic principle is to use the transmission characteristics of radio frequency signals and spatial coupling (inductive or electromagnetic coupling) or radar reflection to realize automatic identification of identified objects. Ⅰ. Understand the RFID reader Radio frequency readers, namely radio frequency identification, automatically identify target objects…
1. Introduction of RFID tags Electronic tag is RFID tag, which is the common name of RFID. RFID is an acronym for Radio Frequency Identification. The organic combination of RFID tag technology and Internet technology is one of the most revolutionary growth points in the global IT industry. The coding method, storage and reading and…
Ⅰ. Introduction of RFID tags With the rapid development of the economy, the application of RFID technology has spread all over the daily life, and has also been integrated into the development of other industries, which has better promoted the development of various fields. As an information recorder, RFID tags have widely appeared in people’s…
For decades, the theory of RFID technology has been enriched and perfected, and active, passive and semi-passive electronic tags have developed rapidly. Single-chip electronic tags, multi-electronic tag reading, wireless readable and writable, long-distance identification of passive electronic tags, and RFID adapted to high-speed moving objects are becoming a reality. 1. Introduction of RFID tags RFID tags…
What is an RFID Antenna? Although each system will vary in device type and complexity, each RFID system contains at least the following four components: reader, antenna, tag, and cable. The simplest systems can consist of mobile handheld RFID readers (with integrated antennas) and RFID tags, while more complex systems use multi-port readers, GPIO boxes,…
When the RFID reader is in use, it can not only read data, but also erase and write data. With the development of RFID technology, RFID card readers can be seen in all walks of life. RFID card readers are mainly used in cargo identification, data collection, etc., and have the characteristics of accuracy, speed,…
Under normal circumstances, the application system of RFID is mainly composed of two parts: the reader and the RFID card. Among them, the reader is generally used as a computer terminal to realize the data reading, writing and storage of the RFID card. It is composed of a control unit, which consists of a high-frequency…
Part of radio frequency identification(RFID) 1. Electronic tags Electronic tags are RFID tags, some of which are called radio frequency tags and radio frequency identification. It is a kind of non-contact automatic identification technology, which can identify the target object and obtain relevant data through radio frequency signals, without manual intervention. As a wireless version…
