Unlike barcodes, which need to be physically visible to the reader or scanner in order to read them, RFID does not. Electromagnetic waves are sent from a tiny antenna on the tag to the scanner. The tag responds by waving. These waves are captured by the scanner, which converts them into digital data. The procedure's nature depends on whether the tag is passive or active. RFID technology Active tags have an internal power source, whereas passive tags depend on energy delivered by the reader.
The
tags bring up a completely new universe of possibilities because they save data
digitally. Businesses can scan more things, expedite shipment, and get more
thorough processing data.
THE PURPOSE OF RFID TECHNOLOGY
RFID technology can lower capital costs, remove human error, and improve operational efficiency. Real-time data is also accessible with RFID tracking, providing knowledge for wiser decision-making and accurate asset management. It employs a tiny chip and incorporates an antenna into a hard physical tag or a primary label for identification.
Line of sight is not required for
RFID
The scanner and each label must be positioned exactly in front of each other and in a precise orientation in order for the barcode to be read. On the other hand, RFID tags don't have to be right in front of an RFID reader. RFID tags just need to be in the reader's read range, which varies depending on the equipment, as they communicate via radio waves.
You can read and write RFID tags
Once printed onto a label, a barcode can only be read, and the data is never altered. RFID tags can be read, and any necessary rewriting or modification of the data is stored there.
RFID tags can be reused and are
strong
Barcodes are frequently printed on paper labels or other uncovered surfaces, which makes them vulnerable to damage and unintelligible. There are RFID tags available that are made expressly to function in challenging environments, depending on your application. These RFID tags are shielded from collisions, heat, moisture, and varying weather conditions by a sturdy hard case. As we previously indicated, the ability to update RFID tracking allows for their reuse, which lowers the cost of your deployments.
Data has been encrypted
Barcodes are simple to fake, yet the data they contain can always be read. Your data is substantially more secure when it is stored on RFID tags since the data can be encrypted. Additionally, it is far more challenging to duplicate RFID tags that have been detected by your system.
RFID tags can store more data
The amount of information that standard barcodes may carry is constrained. An RFID tag can hold up to 8 kilobytes of data in non-volatile memory, where data is actually stored.
Conclusion
Since RFID
technology is still a relatively new technology, there are many things
to take into account before introducing this sort of identification in your
company. However, the advantages may be considerable if it is the proper fit
for your business.
