Everything you ever wanted to know about RFID
One common example of RFID (Radio Frequency Identification) is the pass - like the E-Z Pass - that some drivers keep in their cars so they can drive through tollbooths without having to stop to pay. The chip in the pass sends information to a reader located in the toll booth, and this information, the location, time, and date of the reading are transmitted to a computer system that links to databases containing other information such as the fee for going through the toll and the bank account that’s set up to automatically pay the fee.
RFID technology is also used by companies to track products as they travel from manufacturer to distributor to retailer and many points in between. This helps ensure that safety and quality requirements are met.
