UHF RFID button tags have a built-in UHF chip for sensitive sensing and stable reading and writing. And barcode are used for item identification and tracking technology, but they have some important differences in principle, function, characteristics and other aspects
Differences between RFID button tags and barcode technology
First, RFID technology is a wireless communication technology that utilizes radio waves for data transmission, while barcode technology is an optical identification technology that utilizes light for data reading. This difference makes RFID technology has the ability to read information without direct line-of-sight contact, while barcode technology requires the barcode to be scanned to obtain information.
Secondly, RFID button tags are able to communicate remotely with readers via radio waves, while barcodes can only be read at close range by scanning equipment. This makes the RFID technology has the high efficiency, the rapid at the same time can at the same time recognize many labels the ability, and the bar code technology can only carry on the scanning one by one.
Next, because RFID tags have a unique identification number, individual tags can be programmed to store and update data, as well as track the tag's movement path and status. Barcodes, on the other hand, cannot be programmed and can only passively store information.
Then, RFID button tag reading and writing distance is relatively far, usually a few meters to dozens of meters, or even hundreds of meters, while the bar code technology reading distance is more limited, often only in a few millimeters to dozens of centimeters between.
Compared with bar codes, RFID tags have unique advantages
Long-range scanning
For barcodes, scanning must be done in the vicinity of the label. However, RFID does not require this because the signal can be relayed from further away from the tag. Note that the read range of a passive RFID tag depends not only on the tag itself, but also on the combination of the tag's antenna and the reader used to scan it.
No Line of Sight
With RFID tags, there is no need for line of sight because the scanner can read the tag from anywhere as long as you are within range. This also means that for samples in storage, they can be read without having to be removed.
Multi-Tag Scanning
Instead of having to manually scan each tag, RFID tags can be scanned at the same time, speeding up the workflow.
RFID tags can be rewritten
While bar codes are printed and cannot be changed, RFID tags can be reprogrammed immediately after use. This allows them to be reused for a variety of applications, as labels made with removable adhesives can be peeled off, reprogrammed and affixed to a new series of containers.
Higher Data Storage Capacity
RFID offers greater data storage capacity than bar codes because some tags will allow you to encode small applications that can be used for tasks other than sample tracking, such as electronic payments and access control.
Increased Level of Security
RFID tags can be produced with a unique identification number to prevent counterfeiting and the data on the tag can also be encrypted to provide an additional level of security.RFID can even provide different levels of security on the same tag with both encrypted and open data on the tag.
RFID button tags are applicable in many places due to their small size and high temperature resistance. Such as it can be hidden inside the product, like digital products with a plastic shell, only need to reserve a little space inside the shell, you can put the pill label inside, so that the product is a product with RFID tags. With the induction equipment and system integration, by the product shell fitted with this button label, the product to which a process can be displayed on the computer screen. To the product loaded with electronic tags is equal to the product with an ID card, the production process: encapsulation shell → quality control → warehouse storage → warehouse → after-sales, which product to which process can be easily found, such as defective products, but also can be easily found when the link out of the wrong, whose responsibility it is, at a glance.
