KLIA Ekspres, Malaysia's high speed rail link between Kuala Lumpur and Kuala Lumpur International Airport, implemented a contactless payment system using GHL Systems' technology to allow passengers to tap and pay for their journey using contactless credit cards. The system uses contactless card readers and payment terminals integrated with the boarding gate controls to enable passengers to tap their cards and board the train without needing to queue at ticketing counters. This increased efficiency and provided a more convenient experience for commuters.
