E-ZPass is an electronic toll collection system used on toll roads, toll bridges, and toll tunnels in the Eastern United States, Midwestern United States, and Southern United States. The E-ZPass Interagency Group (IAG) consists of member agencies in several states, which use the same technology and allow travelers to use the same transponder on toll roads throughout the network.
An E-ZPass system transponder unit, also known as a tag or a pack, was distributed by the Massachusetts Turnpike Authority for use with their E-ZPass-compatible Fast Lane system and other roads which utilize E-ZPass.

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods.
