What is the Difference Between RFID Tags and Ordinary Barcode Tags?

Ⅰ. Understand RFID tags


The RFID tag is a non-contact automatic identification technology. It uses radio frequency signals to identify target objects and obtain relevant data. The identification work does not require manual intervention. As a wireless version of barcodes, RFID technology has waterproof, antimagnetic, It has the advantages of high-temperature resistance, long service life, large reading distance, data encryption on the label, larger storage data capacity, and free change of stored information. The electronic tag is the data carrier of the radio frequency identification system. The electronic tag is composed of a tag antenna and a special chip for the tag. What are the advantages of using RFID tags compared to traditional barcodes?


Ⅱ. The advantages of RFID tags compared with traditional barcodes


Compared with traditional barcode identification technology, RFID tags have the following advantages:


1. Quick scan. Barcodes can only be scanned one barcode at a time; RFID readers can identify and read several RFID tags at the same time


2. The volume is miniaturized and the shape is diversified. 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 further miniaturized and developed in various forms to be applied to different products.


3. Anti-pollution ability and durability. The carrier of traditional barcodes is paper, so it is susceptible to contamination, but RFID is very resistant to substances such as water, oil and chemicals. In addition, because the barcode is attached to the plastic bag or the outer carton, it is particularly vulnerable to breakage; the RFID tag stores the data in the chip, so it can be protected from contamination.


4. Reusable. Today's barcodes cannot be changed after being printed, and RFID tags can repeatedly add, modify, and delete data stored in the RFID label, which is convenient for information updates.


5. 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 carry out penetrating communication. Barcode scanners can only read barcodes at close range and without objects blocking them.


6. The memory capacity of data is large. The capacity of one-dimensional barcodes is 50Bytes, the large capacity of two-dimensional barcodes can store 2 to 3000 characters, and the large capacity of RFID tags is several MegaBytes. With the development of memory carriers, the data capacity also has a trend of expanding. In the future, the amount of data that items need to carry will increase, and the demand for expanding the capacity of labels will also increase accordingly.


7. Security. Since RFID carries electronic information, its data content can be protected by a password, so its content is not easy to be forged and altered.
