What is an RFID Chip?

RFID is short for "Radio Frequency Identification." This system uses small tags to track items and store basic information. Tags are attached to important items or even people. When the tag comes within range of a scanner, the stored information can be accessed.

RFID Tags

RFID tags hold basic information and can be made quite small. Some are even implanted into pets for identification or people for security.

RFID Readers

Also called "scanners" or "antenna," RFID readers use radio signals to access the stored information on a tag. Many RFID readers can be used together to cover a large area, such as a highway.

RFID Computer

A computer processes the coded RFID information and makes it readable. It can simply display the embedded information or perform actions automatically, such as debiting a driver's account at a toll station.

Industrial Uses

Common uses of RFID technology in industry include warehouse product tracking, automatic vehicle tolling and location access control.

Live Uses

RFID tags are used on both humans and animals. These uses include race timing, lost pet identification and personal security.
