G8 allows secure payments acceptance in retail stores and on-board planes, trains, buses and ferries. It separates payments processing logic from an EPOS or business application. G8 has been pre-integrated with a wide variety of PIN pads, business applications, payment switches, PSPs and acquirers and can run on tills, PCs, servers, tablets and smartphones.

G8 supports a broad range of payments acceptance functionality, multi-merchant implementations and P2PE. Comprehensive offline transaction processing features make it an ideal choice for airlines and transportation operators.
