Automatic Fuel Dispensers are machines that can be used to deliver fuel to vehicles, normally at a petrol station. These are identified with a specific Merchant Category Code of 5542. The cardholder pays at the machine, normally by inserting their card (or swiping or contactless), and the fuel pump machine will then either:

• authorise a maximum amount (e.g., £100), then pump up to this, and send an advice to say how much fuel was actually delivered (common outside USA).
-or-
• authorise a nominal amount (e.g., 1 USD), then pump up to the permitted maximum it is allowed to clear according to the chargeback rules, then it will send an advice to say how much fuel was actually delivered (common in USA).
