The ACT HOPS (Host or Operator Processing System) is a ticketing transaction processing engine. It is built to the Department for Transport ITSO specification and is certified to version 2.1.4. Most rail and bus smart card schemes in the UK already use our HOPS. It provides the central transaction hub and security for in-the-field hardware such as train station gates, on-bus ticket machines, in-store retail systems and online retail systems.
ACT is the only company that has achieved full HOPS (AMS) certification (without any exceptions) at every release of the ITSO standard since its inception. ACT powers more ITSO ticketing schemes than any other company in the UK, facilitating millions of critical transactions every day.
