RFID equipment is the first priority in today's era!NFC metal manufacture

　　RFID equipment is the perception layer of the core technology of the Internet of Things construction project. RFID equipment is also the core foundation of the application technology of the Internet of Things. The principle of the equipment is a new generation of tag identification technology that emits radio waves through an RFID transmitter, activates the RFID tag oscillation circuit, generates current, and then reads and writes the stored information in the chip. It is a new type of practical technology oriented to the 21st century. In terms of technical application, it carries a large amount of information, does not require contact recognition, can read multiple tags at a time, and can read and write at a high speed. It is more and more widely recognized by the society. How to understand RFID equipment, just read here to understand!

　　At present, several major identifications, barcodes, one-dimensional codes, and two-dimensional codes have their own advantages. Compared with barcode and magnetic stripe technology, RFID tags have absolute advantages. The comparison is as follows:

　　Fast scanning: Only one barcode can be scanned at a time; the RFID reader can identify and read several RFID tags at the same time.

　　Small size and diversified shapes: RFID is not limited by size and shape in reading, and does not need to match the fixed size and printing quality of paper for reading accuracy. In addition, RFID tags can be miniaturized and developed in various forms to be applied to different products.

　　Anti-pollution ability and durability: The carrier of traditional bar codes is paper, so it is easy to be contaminated, but RFID has strong resistance to substances such as water, oil and chemicals. In addition, because the barcode is attached to the plastic bag or the outer packaging carton, it is particularly vulnerable to breakage; the RFID tag stores the data in the chip, so it can be protected from contamination.

　　Reusable: The current bar code cannot be changed after it is printed, and the RFID tag can be repeatedly added, modified, and deleted from the data stored in the RFID tag to facilitate the update of information.

　　Penetration and non-barrier reading: When covered, RFID can penetrate non-metal or non-transparent materials such as paper, wood, and plastic, and can perform penetrating communication. The barcode scanner must be at a close distance and no object blocking the situation before it can read the barcode.

　　The data memory capacity is large: the capacity of one-dimensional bar code is 50 Bytes, the maximum capacity of two-dimensional bar code can store 2 to 3000 characters, the maximum capacity of RFID is several MB, and the current general RFID tag capacity is 1K. With the development of memory carriers, the data capacity also has a trend of continuous expansion. In the future, the amount of information that items need to carry will become larger and larger, and the demand for the expansion of the capacity of the label will also increase accordingly.
