Is RFID better than Barcode?


Compared with barcode card recognition technology, RFID card is a high-end technology and has higher advantages. RFID card is easy to operate, beautiful and durable, so it is popular with the public. Today, DAFTags will introduce to you the difference between RFID card and barcode card.

  • Simply speaking, RFID cards have the following advantages:
1. Quick scanning
Only one barcode can be scanned at a time; the RFID reader can identify and read several RFID tags at the same time.

2. 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 the paper for reading accuracy. In addition, RFID tags can be miniaturized and developed in various forms to be applied to different products.

3. Anti-pollution ability and durability

The carrier of traditional bar codes is paper, so it is easily contaminated, 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 packaging 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

Nowadays, the barcode cannot be changed after it is printed, and the RFID tag can repeatedly add, modify, and delete the data stored in the RFID tag to facilitate the update of information.

5. Penetrating and barrier-free reading

When covered, RFID can penetrate non-metallic 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.

6. Large data memory capacity

The capacity of a one-dimensional barcode is 50Bytes, the maximum capacity of a two-dimensional barcode can store 2 to 3000 characters, and the maximum capacity of an RFID is MegaBytes. With the development of memory carriers, the data capacity also has a trend of continuous expansion. In the future, the amount of data that items need to carry will become larger and larger, and the demand for the expansion of the capacity of the label will increase accordingly.

7. Security

Since RFID carries electronic information, its data content can be protected by a password, making its content difficult to forge and alter.

Nowadays, wireless radio frequency card technology has attracted much attention due to its long-distance reading and high storage capacity. It can not only help an enterprise greatly improve the efficiency of goods and information management, but also connect sales companies and manufacturing companies, so as to more accurately receive feedback information, control demand information, and optimize the entire supply chain.
