RFID v/s Bar Codes
RFID definitely has an edge over conventional technology of bar codes. RFID reader easily pulls data from tag at greater distances as compared to barcodes. Range in case of RFID is around 300 feet as against 15 feet of barcodes. So RFID tags can be read much faster as compared to barcodes. While reading the barcodes is time consuming, RFID readers can interrogate rates of more than 40 tags in a second.
Need of line of sight in case of barcodes restricts reusability and ruggedness of the barcodes. RFID, on the other hand are rugged, since its components are protected in plastic cover. The Radio frequency Identification and Detection can also be fitted within the products for ensuring greater reusability and ruggedness. Unlike barcodes, RFID tags can be used as write and read devices. One can use RFID tags for communicating with the tag and for altering the information stored on it.
