WHAT IS RFID?
HOW CAN IT BE USED?
Traditional barcodes are still relevant in today's world, and will continue for a long time to come. RFID is not intended to replace barcodes, but rather to enhance tracking without the need for line of site.
Traditional Barcode - Line of Sight
RFID Reader - Radio Waves
Barcodes can only be read with "line of sight" by a barcode scanner, whereas RFID uses radio waves and does not require a line of sight. Barcodes contain a certain set of informational data, and this data is "read only". It can be read many times, but the data cannot be changed without changing the barcode. RFID tags have read and write capabilities. Some tags send out a signal in search of an RFID reader, while others react to a reader seeking a signal.
So how can this help me, you ask? Here are just a few of the most common applications for RFID technology:
