Gasboy Tag Reader - Manual (Page 9)

Two LEDs on the Tag Reader front panel indicate the transaction status:
Green –  - Positive recognition, transaction was authorized
Red –  - Negative recognition, transaction is not authorized.
The indicators are automatically activated by the station Controller when the customer places the
tag or card near the tag reader, close to the sensing component located at the bottom of the front
panel (see Figure 1-1).
A welcome message is displayed on the TR display, and is replaced by messages which indicate the
progress of the transaction. The display is backlit for improved readability under poor lighting
conditions. An internal speaker provides audio feedback.
