In recent years, mobile phone operators made a huge success offering mobile phones without subscription. Telecommunication fees are pre-paid and loading of limits is carried out by activation of so called tele-codes, namely numeric codes.
Traditional distribution of tele-codes in the form of scratch cards is expensive and exposed to misuse. Moreover, it is limited by the defined number of nominal values.
The solution is to pay for services, namely to load the limits, electronically. PROCARD elaborated and implemented its own solution covering terminal application enabling to pay for the service – loading of limits, in defined nominal value (so called Vauchers) and in any value (called Top-up).
Terminal application may also be used for other pre-paid services.
Terminal application is the element of the entire system covering software of tele-code distributing centre interoperating with GSM phone operators.
