Comparison of Radio Frequency Identification Technology and Bar Code
Why is RFID technology superior to barcodes? RFID technology and bar code are two different technologies, have different applicable scopes, and sometimes overlap. The biggest difference between the two is that barcodes are 'visual technology'. The scanner works under the guidance of people and can only receive barcodes within its field of view. In contrast, radio frequency identification does not require seeing the target. The radio frequency tag can be read as long as it is within the range of the receiver.

The barcode can only identify the producer and the product, but cannot identify the specific product. The barcodes affixed to all the same product packaging are the same, and it is impossible to identify which products expire first. What is the difference between RFID technology and barcode? Conceptually, the two are ver...
