1. Quick scan
The barcode can only be scanned at one bar at a time; the RFID recognizer can simultaneously recognize and read several RFID tags.
2. Small size and diverse shape
RFID is not limited in size and shape for reading, and does not need to match the fixed size and print quality of the paper for reading accuracy. In addition, RFID tags can be developed into smaller and more diverse forms for use in different products.
3. Anti-pollution ability and durability
Traditional bar code carriers are paper and are therefore susceptible to contamination, but RFID is highly resistant to substances such as water, oil and chemicals. In addition, since the bar code is attached to a plastic bag or an outer carton, it is particularly susceptible to breakage; the RFID tag is to store data in the chip, so it can be protected from fouling.
4. Reusable
Nowadays, barcode printing cannot be changed after it is printed. RFID tags can repeatedly add, modify, and delete data stored in RFID tags to facilitate information update.
5. Penetrating and barrierless reading
In the case of coverage, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and can communicate transparently. The barcode scanner must be able to read the barcode at close range without object blocking.
6. The data has a large memory capacity
The capacity of a one-dimensional barcode is 50 Bytes, the maximum capacity of a two-dimensional barcode can be stored from 2 to 3000 characters, and the maximum capacity of RFID is several MegaBytes. With the development of memory carriers, the data capacity has also been expanding. The amount of information that will be carried in future items will increase, and the demand for capacity expansion of the volume label will increase accordingly.
7. Security
Since RFID carries electronic information, its data content can be protected by passwords, making its content difficult to be forged and altered.
In recent years, RFID has attracted attention due to its long-distance reading and high storage capacity. It can not only help a company to greatly improve the efficiency of goods and information management, but also enable sales companies and manufacturing companies to interconnect, so as to more accurately receive feedback information, control demand information, and optimize the entire supply chain.
