RFID handhelds have a wide range of applications in transportation, access control, logistics, attendance, cargo management, and identity recognition. RFID handheld devices have higher requirements on the efficiency, service life, reliability, volume, and cost of the power supply. Therefore, designing a power supply with good stability, high efficiency and small stray is of great significance for RFID handsets.
In the RFID system, the RFID handheld terminal emits electromagnetic waves in a specific area, and the size of the area depends on the size of the antenna and the operating frequency. The LC series resonant circuit is arranged in the radio frequency card, and its frequency is the same as the frequency transmitted by the handheld terminal.
Now on the market, RFID products can be seen everywhere, rfid tags, rfid handsets, rfid readers and so on have been common. What are the common RFID handheld terminals on the market?
I don't know if you have encountered it in the supermarket. The supermarket staff scans the barcode label of the item with PDA, changes the product price, and then prints the price and pastes it on the product to complete the product price change. The above price change job is simple and easy to do, but a lot has been done.
RFID is widely used in various industries, and reinforced three-proof tablet computers with RFID function have also been derived in the market. Now there are two main types of RFID three-proof reinforced tablet computers on the market. One is to attach the RFID module through the back clip. In the form of accessories, it is fixed on the back of the tablet computer through the pogopin interface.
With the rapid development of the animal husbandry industry, the level of scale and specialization has been continuously improved. Transforming and upgrading traditional animal husbandry, pioneering and innovating modern intelligent animal husbandry, and accelerating the modernization and informatization construction of animal husbandry have become more and more important factors in the development of animal husbandry.
By using RFID to detect asset locations, hospitals can make it easy for staff to find the closest needed equipment. This visibility also makes it easier to identify idle assets, thereby avoiding unnecessary asset purchases. Such tracking could also increase the utility of the FDA's Unique Device Identifier (UDI) requirement for tracking medical devices.
The highway automatic toll collection system is one of the most successful applications of RFID technology. At present, the development of expressways in China is very fast. The prerequisite for regional economic development is to have convenient transportation conditions. However, there are some problems in expressway toll collection.
In view of the problems existing in the traditional logistics distribution center, how to apply RFID technology in the distribution center is introduced in detail from one of the following aspects.
Unique code management, tracing the source of each commodity and eliminating counterfeits; The label is embedded in each item, and the whole box is quickly sensed to realize full-automatic receiving; Instantly verify picking errors, and 100% eliminate excessive, insufficient and wrong picking; Batch induction inventory, the inventory frequency of the store can be greatly improved, and it is no longer a dream to achieve 100% consistency between the account and the actual;
