The innovative digital solution will see the end of traditional paper vouchers, instead “instantly adding value to passengers’ boarding cars, smartphone passes or frequent flyer cards”.

The paperless solution, which does not require integration with an airline, will also automate the administration of vouchers, enabling detailed reporting and simplified billing between retailer and airline.

The solution is completely controlled by the issuing airline, taking seconds to allocate a chosen monetary value to an existing barcode already in a passenger’s possession, such as the code on a boarding pass.

Richard Bye, founder of iCoupon, said: “We have created a technology able to automate one of passengers’ biggest bugbears when things go wrong – the queueing. We have automated the process, enabling passengers to remain relaxed and comfortable.

“Adoption of iCoupon by retail and airline customers has been rapid. Airports embrace the technology because it removes the surge of passengers moving around terminals and passenger feedback is exceptional.”

iCoupon is currently live in close to 100 airports across Europe and has an expansion plan for 2017 across Europe, Asia and the US.

Several airlines and ground handlers including Ryanair, Jet2, Finnair and Swissport are already using the smart solution.

Joanne Brady, ground operations control manager for Ryanair, said: “iCoupon eliminates the need for traditional paper vouchers, allowing a faster, cost effective and greener service, and providing assistance to customers in a matter of seconds."
