What benefits does RFID have over barcodes?
The most obvious benefit is that RFID does not have to be seen to be read. Bar codes must be placed on the outside of the product and the product must be orientated so the bar code is inline with the scanner. On the other hand, with RFID, you could have (multiple) products inside a sealed carton (for example) and each product can still be identified. Another important difference is that RFID is a read/write technology. So if desired the data can be written (or programmed) after it has been attached to the product. This offers a higher level of flexibility to track and update the data as the product goes through the supply chain, into the end use application or beyond.
