What is the difference between rfid electronic label and barcode?
The difference between rfid electronic label and bar code
1. Tag reading
Reading barcodes is time-consuming and requires close-range reading. If the object is not facing the reader correctly, it cannot be read. Bar code readers usually require half a second or more to successfully read a label.
RFID reader can read Blanders RFID tags faster; reading rate can achieve up to several hundred tags per second.
Bar code is marked by the thickness of the printed bar, and the number is known by optical means.
RFID tags can be considered as the electronic version of the bar code, its working principle is the radio principle, through the electromagnetic wave carrier, modulation and other processes to obtain the number information in the RFID tag chip
3. Label usage environment
Barcode alignment and reading requirements limit the durability of the bar code and also limit its reusability. Paper-printed barcodes, under severe conditions, damaged barcodes, frost and snow-covered, and water-damaged barcodes cannot be read.
RFID tags are usually more durable and will not be affected by the environment, can withstand high temperatures and water, acid and alkali and other harsh environments.
4. Label anti-counterfeiting capability
The content of the barcode cannot be changed, but it can be copied and reused.
RFID tags are not like barcodes, their unique identifiers cannot be copied, they are unique numbers. The content of the label can be read and written repeatedly.
5. Label storage capacity
Barcode data capacity The stored data capacity is small, only a few hundred bytes.
RFID data storage: Compared with the traditional form of tags, the capacity is large (1-1024bit), and the data can be updated at any time.
1. The working principle is different
Radio frequency identification technology uses rapid information exchange and storage technology through radio waves without contact, combined with data access technology through wireless communication, and then connects to a database system to achieve non-contact two-way communication, so as to achieve the purpose of identification, used for data exchange, An extremely complex system is connected in series. In the identification system, read, write and communication of electronic tags are realized through electromagnetic waves.
Barcode technology was born with the development and application of computer and information technology. It is a new technology integrating coding, printing, identification, data collection and processing.
2. Different functions
Barcode is a graphic identifier that arranges multiple black bars and blanks with different widths according to a certain coding rule to express a set of information. A common bar code is a parallel line pattern composed of black bars (referred to as bars) and white bars (referred to as empty) that differ greatly in reflectivity.
RFID is a radio frequency identification technology that performs non-contact data communication between readers and tags to achieve identification targets.
3. Different applications
The application of RFID is very extensive. At present, typical applications include animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, and material management.
The bar code can indicate the country of manufacture, manufacturer, product name, production date, book classification number, mail start and end location, category, date and other information of the item, so it is in many fields such as commodity circulation, library management, postal management, banking system, etc. It is widely used.
