Before we get into the advantages of radio frequency identification (RFID) over traditional barcode technology, let’s do a quick overview of both:
Barcodes are a series of machine-readable, parallel black bars that represent identification information. The information is encoded by varying the widths of the bars and the distances of the spaces between each bar. An optical barcode scanner then translates the information for further interpretation.
RFID products use unique radio waves to communicate information. Typical industrial RFID systems consist of an RFID reader (head), RFID interface (controller), and RFID tags (transponders).
