Welcome to RFID 101
RFID (Radio Frequency IDentification) allows data to be transmitted by a product containing a 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.
Do you understand RFID?
Unlike ubiquitous UPC bar-code technology, RFID technology does not require contact or line of sight for communication. RFID data can be read through the human body, clothing and non-metallic materials.
RFID is in use all around us. If you have ever chipped your pet with an ID tag, used EZPass through a toll booth, or paid for gas using SpeedPass, you've used RFID. In addition, RFID is increasingly used with biometric technologies for security.
RFID technology also works in rain, snow and other environments where bar code or optical scan technology would be useless.
