Overview
The Transmitter/Receiver IN Dispenser (TRIND) system is similar to the technology
successfully used by many toll ways. It uses an electronic system located in the pump or
register to “talk” with a miniature radio-like device (a tag). Together, these electronic devices
provide “cashless” access to gasoline, food, and merchandise by charging purchases to a credit
card, check card, or other account you already have. The TRIND system operates on a
dedicated tag identification code. Your credit card or check card account numbers are not
typically used with the tag signal system, which protects your account from unauthorized use.
And if your tag is ever lost or stolen, your liability is limited to the amount set by your
financial institution.
The TRIND device is an option available as a retrofit kit or factory installed device for The

lines of fuel dispensers. The device is
connected to the Card Reader IN Dispenser (CRIND)
®
device via a Gateway or serial interface
board. In this application, the TRIND device is a software slave to the CRIND and the
associated Point of Sale (POS) Controller/Host. This means that a properly working TRIND
system will look for and read tags, but only when “told” to by the controller, through the
CRIND application.
About TRIND
The TRIND devices are developed to utilize Texas Instruments Radio Frequency
Identification (RFID) technology. These devices provide two-way communications between
an interrogator system in the fuel dispenser and the consumer’s hand-held or car mounted
transponder tag. This two-way communication authorizes and records sales, eliminating the
need for the consumer to engage in a cash or credit card transaction.
