According to a study, the global retail RFID application market is expected to reach US$3.91 billion by 2019. The global RFID market for such applications will grow at a compound annual growth rate of 40%. Conceptually, Rfid Tags barcode technology. Bar code technology generally attaches barcode information to an item, and scans the barcode on the item by a scanner to obtain information of the item. The RFID technology attaches Rfid Tags
to the item, and reads the information in the tag into the RFID reader through the RF signal, thereby obtaining the unique information of the item. Compared to traditional barcodes, the advantages of FRID technology are as follows:
1, fast scan
The RFID recognizer can recognize and read multiple RFID tags, and only one bar code can be scanned at a time.
2, penetrating and barrier-free reading
In the case of being covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and can communicate transparently. The reason why "unmanned supermarkets" can achieve unoccupied cash is actually the use of RFID technology.
3, the data has a large memory capacity
The capacity of the one-dimensional barcode is about 30 characters, the maximum capacity of the two-dimensional barcode can be stored from 2 to 3000 characters, and the maximum capacity of the RFID is several mega-characters. With the development of the memory carrier, the data capacity is also expanding.
4, small size, diverse shapes
RFID is not limited in size and shape for reading, so it is not necessary to match the fixed size and print quality of the paper for reading accuracy, unlike the problem that the barcode is prone to deformation and breakage, which is unrecognizable.
