At present, the bar code-based production management system conveniently realizes various quality analysis and control. The traditional barcode system has its advantages and obvious disadvantages, such as easy contamination, damage, and the need to stop and wait for scanning one by one. Moreover, the batch reading efficiency is not high, and cannot meet the needs of fast and accurate. Compared with traditional barcode recognition technology, what are the essential advantages of RFID technology?
RFID radio frequency technology can quickly identify and read long-distance, accurate, and large storage capacity. It can meet the needs of various enterprises to improve their products and improve the efficiency of information management. It can also enable distributors and manufacturers to quickly interconnect information, and receive and respond to information in a timely manner. However, although the traditional barcode is low in cost, it cannot identify multiple tags, has a small information capacity, and is unsafe.
Compared with traditional barcode recognition technology, RFID has the following advantages:
1. Quick scan
Only one barcode can be scanned at a time; the RFID identifier can simultaneously recognize and read several RFID tags
2. Miniaturized size and diversified shapes
RFID is not limited by size and shape when reading, and the reading accuracy does not need to match the fixed size and print quality of the paper. In addition, RFID tags can be miniaturized and diversified to be applied to different products.
3. Anti-pollution ability and durability
The carrier of traditional bar codes is paper, which is easily contaminated, but RFID is very resistant to water, oil, and chemicals. In addition, because the barcode is attached to the plastic bag or the outer packaging carton, it is particularly easy to be damaged; the radio frequency identification tag stores the data in the chip, so it can prevent pollution.
The current barcode cannot be changed after printing, and RFID tags can be added, modified, and deleted repeatedly
The data stored in the RFID tag is convenient for updating information.
5. Penetrating and accessible reading
In the case of being covered, RFID can penetrate non-metallic or opaque materials such as paper, wood, plastic, etc. for penetration communication. However, barcode scanners can only read barcodes at close range and no objects obstructing them.
6. The data storage capacity is large
The capacity of one-dimensional barcode is 50 bytes, the maximum capacity of two-dimensional barcode can store 2 to 3000 characters, and the maximum capacity of RFID is several megabytes. With the development of storage media, data capacity is also expanding. In the future, the amount of data that items need to carry will become larger and larger, and the demand for expandable capacity of tags will increase accordingly.
Since RFID carries electronic information, its data content can be protected by a password, so that its content is not easily forged or tampered with.
In recent years, RFID has attracted much attention due to its long-distance reading and high storage capacity. It can not only help companies greatly improve the efficiency of product and information management, but also connect sales companies and manufacturing companies to more accurately receive feedback information, control demand information, and optimize the entire supply chain.
