Managing a queue is much more serious problem when the time required to serve a person cannot be predetermined. This is very much true in case of health care services where the time taken depends on type of disease, interaction with the patient etcThe least that patient expects is to get served on first come first serve basis. To ensure this one of the methods that was traditionally followed was to handover recycled tokens to the patients walking in and make them meet concerned consultant on being called. This manual process is very tedious and prone to human errors, suspicion of tampering and communication problems among hospital staff. Such problems made it necessary to have automatic Token Management System in place.

The system usually consist of more than one calling unit and a display unit. Token Dispensers are employed to get the token printed and to register service request. All these units are connected to the central controlling unit called Token Hub  Token can have upto 8 services. A separate hot key will be there for each service.
