Current Situation and Future Trend of RFID-1.3 Classification of RFID tags

According to the internal structure of RFID tags, they are divided into active tags with battery (Tony Note: Also called active tags) and passive tags without battery (Tony Note: Also called passive tags) these two types. The Passive Tag uses the radio waves sent by the reader as the power to start the IC circuit. Therefore, it has the advantage of semi-permanent use, but the communication distance is shorter than that of the active tag. On the other

Current Situation and Future Trend of RFID-1.7 antenna shape and material of RFID tags

Antennas are rectangular, circular, and rod-shaped. Generally, the longer the communication distance is, the larger the size of the antenna. However, in actual use, when tags are attached to an item, even the RFID tags of the business card size are too large. In fact, the size and shape of the RFID tag in use need to be selected based on the communication distance. Currently, antenna materials include al

Current Situation and Future Trend of RFID-1.6 antenna types and features of RFID tags

× Winding Process It is a process that combines an antenna and an IC loop to form a module. It takes some time to mount modules one by one on a thin board. Therefore, high costs are not suitable for mass production. However, compared with other manufacturing processes, the tag communication distance is improved. × Etching ProcessIt is a process of forming an antenna by etching aluminum or copper film on the pet Film Board. Figure 4 shows an item (using an etching antenna in an IC circuit). B

A small view on "RFID security technology discussion"

MIFARE Classic series cards were not cracked. At this time, the author of the question refers to the analysis of the card data.RFID attacks are intended for RFID security vulnerabilities. The author focuses on the data analysis of e-wallet to describe the simulation of RFID attacks. We cannot see the real vulnerabilities

Four measures to ensure RFID credit card security

The worry about RFID security is not new. However, these concerns grew when the US MRT company and Chase started issuing RFID-enabled credit cards last year. The fear escalated when researchers at the University of Massachusetts announced in October this year that they had breached the credit card RFID security feature. RFID

Overview The library needs to upgrade the software and hardware of the library management system by using advanced RFID Wireless RF cards) technology and equipment, this effectively improves the efficiency of book management, simplifies the process of book management, and reduces the labor intensity of book management personnel. The library RFID automatic management system can be used as an independent l

How does RFID affect the supply chain of the manufacturing industry?

RFID is revolutionizing the inventory tracking method in the supply chain. This technology ensures that the right products reach the customer's hands as needed and that the inventory of the distribution center is controlled at the optimal level.For manufacturers, RFID technology is bringing about labor savings and operational efficiency improvement, thus increasing the operating income of the entire product

RFID security technology

Frequent RFID attacks In recent years, there have been frequent RFID attacks at home and abroad. Some hackers have used RFID technology to crack various consumer cards, recharge cards, and then maliciously recharged consumer cards. Some of them have been sentenced. Currently, Iot is driving the development of mobile Internet. Many mobile terminals are also emb

Iot, as its name implies, is the Internet of Things. Iot is developed on the basis of the Internet. People are the subjects on the Internet, while Iot is specific things that are extended to human life, such, A car, a bed, a microwave oven, or even a house. Any object can be covered in this network, so as to realize information exchange between things and between people, so as to achieve intelligent identification, positioning, monitoring and management of the object. One of the core Iot technol

QR code and RFID

[QR code] It is a new generation of bar code technology that records data symbol information using black and white rectangular phalanx distributed in a plane (two-dimensional direction) according to a certain rule, it consists of a QR code matrix and a QR code number, as well as the instructions below. You can read a large amount of information in the QR code through a dedicated QR code reading device or smartphone. It features a large amount of information, strong error correction ability, fa

RFID tags can be divided into low frequency (LF), high frequency (HF), and ultra high frequency (UHF)

For an RFID system, the concept of Frequency Band refers Frequency Range of tag signals sent, received, and read by the reader through an antenna . In terms of application concept, the operating frequency of the RF tag, that is, the operating frequency of the RFID system, directly determines all aspects of the system application. In an RFID system, the system wor
