High-flying West Midlandsbased handheld technology firm Initium has seen demand soar for its state-of-the-art software.
The company, which develops software for handheld computers, has won three major aviation contracts.
Delta Airlines, BMIBaby and Gulf Air have all signed up to use the high-tech gadgets on their aircraft.
Delta, a major airline in the United States, has rolled out 300 of the devices for in-flight duty free sales. The system has been on board the aircraft since April.
Bahrain-based Gulf Air is also using the mini computers for duty free sales, and it has ordered 100 to go on its fleet from July.
No-frills airline BMIBaby, which operates flights out of many UK airports - including Birmingham International - started utilising them for the sale of food and drink on planes in June.
The handheld computers are used like a portable till by cabin crew to scan in, add up the price of items, carry out automatic currency conversion for payments and calculate discounts such as meal deals.
Keith Neville, managing director of Initium, said the technology had many advantages to cabin crew.
"This system is fast and very efficient and eliminates the laborious form filling previously required - making things a lot easier for the cabin crew," he said.
"The software is adapted for the latest technology by using touch screen and swipe card methods, and the information can be downloaded after the flight via a docking station or remotely via wireless or GPRS."
Initium has recently moved from the University of Warwick Science Park's Business Innovation Centre in Binley into new premises at its Warwick Innovation Centre.
The company has also accessed business support services that the science park offers to its tenants and other local companies.
