RFID is the abbreviation of Radio Frequency Identification. The principle is non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID has a wide range of applications. Typical applications currently include animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, and material management.
RFID technology relies on electromagnetic waves and does not require physical contact between the two parties. This enables it to establish a connection regardless of dust, fog, plastic, paper, wood, and various obstacles, and directly complete communication
The read and write speed of the RFID system is extremely fast, and a typical RFID transmission process is usually less than 100 milliseconds. The high frequency RFID reader can even identify and read the content of multiple tags at the same time, which greatly improves the efficiency of information transmission
Each RFID tag is unique. Through the one-to-one correspondence between the RFID tag and the product, the subsequent circulation of each product can be clearly tracked.
The RFID tag has a simple structure, a high recognition rate and simple reading equipment. Especially with the gradual popularity of NFC technology on smart phones, each user’s mobile phone will become the simplest RFID reader.
Logistics warehousing is one of the most potential application areas of RFID. International logistics giants such as UPS, DHL, Fedex, etc. are actively experimenting with RFID technology in order to improve their logistics capabilities on a large scale in the future. Applicable processes include: cargo tracking in the logistics process, automatic information collection, warehouse management applications, port applications, postal packages, express delivery, etc.
There have been many successful cases in taxi management, bus terminal management, railway locomotive identification, etc.
RFID technology is widely used in personal identification documents because of its fast reading and difficult to forge. Such as the current electronic passport project, my country's second-generation ID card, student ID and other various electronic documents.
RFID has the characteristics that it is difficult to forge, but how to apply it to anti-counterfeiting still requires active promotion by the government and enterprises. Applicable fields include anti-counterfeiting of valuables (tobacco, alcohol, medicine) and anti-counterfeiting of tickets, etc.
It can be applied to the management of all kinds of assets, including valuables, items with large quantity and high similarity, or dangerous goods. As the price of tags decreases, RFID can manage almost all items.
At present, RFID tags have gradually begun to expand the market scope, which will be a development trend and industry development direction in the future.
Our company currently has 3 types of multifunction machines, their models are respectively LQ-A6000, LQ-A7000, LQ-A6000W label lamination. Inlay and label can be combined to form a complete product.
