Gasboy Tag Reader - Manual (Page 11)

1-3.2.2. Magnetic Stripe Fuel Cards
If the TR is equipped with an optional magnetic card reader, at the right-hand side of the unit, the
driver can use a magnetic stripe card.
A magnetic stripe card is a type of card capable of storing data. The magnetic stripe is read by
physical contact and swiping past a reading head.
The driver may have a vehicle fuel card or personal driver card.
1-3.2.3. Payment Contact Less Cards (optional)
Payment contactless cards such as the PayPass® cards enable the driver to pay using a standard
credit or debit card which has contact less capabilities.
This allows the home-base station to be semi-public and accept payment from occasional customers
and process the transaction through the bank or local processing network.
TR has an optional PayPass reader to support these types of cards
1-3.3. Serial Communication Interface
The TR has a balanced bidirectional RS-485 communication interface, which connects to the CFN
PLUS of the gas station or tanker truck.
This interface is used to communicate with the station controller.
The power and communication cable has five wires: two power supply wires, two wires for the
communication interface and one Ground Wire (see
Figure 1-3).
