Outdoor payment terminal (OPT) for private filling stations. Ideal for companies who use and store large quantities of fuel in their operation. Fuelling requires a successful multi-factor identification (RFID cards are supported) and the input of the number plate and odometer info. The purchasing data is forwarded to a centralized database for record keeping and analytic purposes. The MemoTank can even manage multiple companies' fuel in a shared tank. A commercial diesel tax refund can also be claimed when using our OPT.
