FIELD: information technology.
SUBSTANCE: method includes a step of receiving a request for access to a location at a gate access device from a user. After receiving the request for access to the location, an authorisation request message is generated. The authorisation request message includes an authorisation to charge a predetermined amount of money. The authorisation request message is then sent to an issuer for approval. An authorisation response message is then received. The authorisation response message indicates whether the charge is authorised or not. If the authorisation response message indicates that the authorisation response message is authorised, the user is then allowed to access the location.
EFFECT: high reliability and safety of providing access to a location through a real-time authorisation process.
