The iZak system, from iZAK is designed to allow flight crews to pay for fuel without having to visit the FBO's front counter. Fuel truck drivers carry a handheld computer with a color touchscreen, card swipe device, and a wireless printer. After the aircraft is fueled, the meter readings and tail number read directly from Veeder-Root fuel meters and then wirelessly transmit to the FBO's base computer. Cornerstone Logic's FBO Manager software calculates the price of the transaction, including any discounts. The line technician may then swipe a credit card on site, printing out a receipt on the spot; www.IZAK.INFO.
