Self-service Entrance Guard System of College Library Based on RFID Smart Card

Image
The library access control system is a control system that guarantees the safety of book resources and improves the management efficiency and management level of the library. With the support of computer technology, network technology, and target recognition technology, there are currently many library access control systems on the market, but most of these access control systems are customized and developed according to different library informatization conditions. Because of the original books The structure of the library management system is different, which makes the link between the access control system and other management systems of the library very inconvenient. In addition, the functions of most library access control systems remain at the level of security management and automatic loan and return. In order to realize the seamless link between the access control system and various digital libraries, expand the functions of the access control system, and improve the self-serv...

Application of Gallium Nitride in Radio Frequency Electronics

Image
In recent years, due to the application of 5G, everyone's attention to RF GaN has increased. Qorvo also believes that GaN is very suitable for providing the high frequency and wide bandwidth required by the millimeter wave field. It can meet the performance and small size requirements, as shown in the figure below. Applications that use the millimeter wave frequency band require highly directional beamforming technology (beamforming focuses the radio signal into a strong directional beam, thereby increasing power and minimizing interference on user equipment). This means that the RF subsystem will require a large number of active components to drive a relatively compact aperture. GaN is very suitable for these applications, because it provides strong performance in a small package size is one of its most notable features. According to a report by Yole, an internationally renowned analysis organization, in early June, the GaN radio frequency industry started with silicon carbide-bas...

What are the new opportunities for RFID in the post-epidemic era?

Image
Although the business society already has a stable and complex structure, the changes in the market always make people wonder. Since 2020, a new crown epidemic has caused a huge impact on the global economy, and almost all industries have been severely affected. The first thing the epidemic comes is is a crisis, but the crisis often gives birth to new opportunities for development. For the RFID industry, the emergence of the epidemic on the non-contact economy is an opportunity, gestating new growth points. Under the influence of the epidemic, many industries have become more aware of the benefits of RFID. For medicine, the use of RFID technology can realize the traceability management of medicine and medical equipment, and the realization of these functions is based on non-contact. Therefore, in the post-epidemic era, the value of using RFID technology to improve the medical management system has been seen by more and more hospitals and medical organizations. The impact of the epidemi...

In Which Areas Is RFID Technology Applied?

Speaking of RFID , in fact, it is widely used, and it is even used every day, such as our second-generation ID card. Mr. Xuetang said that the application of RFID in daily life is good~+RFID (Radio+Frequency+Identification, radio frequency identification) is a wireless communication technology that can automatically identify target objects and obtain related data through radio frequency signals. It is the Internet of Things One of the commonly used short-range wireless communication technologies. +RFID electronic tags have a complete set of modulators, encoders, memories, controllers and antennas, according to application requirements, you can choose the built-in battery to work together. +Compared with ordinary bar codes, RFID technology has the advantages of waterproof, anti-magnetic, high temperature resistance, long service life, long reading distance, encryption of label data, and larger storage capacity that ordinary bar codes do not have. +The electronic tag can realize the read...

What Is RFID Technology?

The radio signal recognizes a specific target and reads and writes related data, without the need to establish mechanical or optical contact between the recognition system and the specific target. The radio signal is an electromagnetic field tuned to a radio frequency to transmit data from the tag attached to the item to automatically identify and track the item. Some tags can obtain energy from the electromagnetic field emitted by the recognizer during identification, and do not require a battery; some tags have their own power source and can actively emit radio waves (electromagnetic fields adjusted to radio frequencies). The label contains information stored electronically and can be identified within a few meters. Unlike the barcode, the radio frequency tag does not need to be in the line of sight of the recognizer, and can also be embedded in the tracked object. Expansion information: Many industries have used radio frequency identification technology. By attaching the label to a ...
