What is the purpose of RFID?
RFID allows data to be transmitted by a product containing an RFID tag microchip, which is read by an RFID reader. The data transmitted can provide identification or location info about the product, or specifics such as date of purchase or price.
What is the advantage of using RFID technology?
No contact or even line-of-sight is needed to read data from a product that contains an RFID tag. This means no more checkout scanners at grocery stores, no more unpacking shipping boxes, and no more getting keys out of your pocket to start your car. RFID technology also works in rain, snow and other environments where bar code or optical scan technology would be useless.
Will RFID replace UPC bar code technology?
Probably not, at least not soon. Besides the fact that RFID tags still cost more than UPC labels, different data capture and tracking technologies offer different capabilities. Many businesses will likely combine RFID with existing technologies such as barcode readers or digital cameras to achieve expanded data capture and tracking capabilities that meet their specific business needs.
