RFID Tags Versus Barcodes: Which Are Better and Why?
A barcode is a graphical representation of data interpreted and scanned for information. Each barcode has a code which works as a monitoring technology for the products. It is represented in a line or other shape sequence. While initially, the technology involves using one dimensional parallel lines, now even 2D rectangles and other shapes are used for barcodes. Barcode technology can be scanned by not just readers, but smartphones and desktop printers as well.
RFID, on the other hand, is way better, which is why so many companies worldwide use it. It involves a tag attached to a product or subject, which tracks the object through radio waves. RFID tags can carry over 2,000 bytes of data. This 3-part technology involves a decoder, transceiver and scanning antenna to interpret data and a transponder or RFID tag pre-set with information. Scanning antennas send out radio frequency signals to communicate with the tag. When the tag passes through the frequency field, it activates the signal and transfers the information to be picked up by the antenna.
RFID Versus Barcodes: Which is Better & Why?
RFID tags are preferred, as these can be read from a greater distance than barcodes. Additionally, these don’t need to be placed in the line of sight with the scanner, if walk-through technology is being used. Also, RFID tags can be read at a much faster rate than barcodes. Close to 40 RFID tags can be read simultaneously.
Further, RFID tags can work across larger distances, with information read from tags at a wider range compared to barcodes. RFID tags are also read and write devices. These offer higher security because data can be encrypted, password protected or set to include a kill feature to remove information in a permanent way.
RFID tags carry larger data capabilities ; these can be programmed to the tag. Once these are set up, no human help is needed. Further, RFID tags for even educational use as they are more reusable and rugged as well as protected by a plastic case.
Why Barcode Technology Fails
Barcode scanners further need direct line of sight to the tag to be able to read the barcode; in fact the scanner has to be no more than 15 feet away! Additionally, barcodes lack red and write capabilities and do not contain information such as expiry date. These involve use of human assistance too. A person actually has to scan the barcode.
It cannot be done automatically like RFID tags. Barcodes offer less security besides this and are more easily damaged. If the barcode is damaged or ripped, there is no way left to scan the product.
RFIDs offer numerous advantages over barcodes and remain the better choice. RFID is faster than barcode scanning. Because it uses near field technology rather than line of sight, the RFID technology can work more easily. Fixed RFID scanners can be placed at strategic points to register movement. In real-world settings, RFIDs show more accuracy than barcodes.
Also, barcodes can be easily tampered and the data is readable. In contrast, RFID tags are encrypted and impossible to replicate. Further RFID tags also store more data. Barcodes need to be individually scanned to be entered into systems. RFID systems can read numerous tags in one go. The ultimate advantage of RFID? It can easily be used alongside a barcode!
