Voucher Management System
Account recharging via voice services
PROTEI Voucher Management System allows your subscribers to recharge their accounts from their own telephone as well as from any tone-dial phone.
Account recharging via non-voice services
Subscribers can top up their own accounts, as well as the account of any other subscriber of the same network, by sending an SMS or USSD request with a PIN code to a service number. Accounts can also be recharged from a special website.
Account recharging via operator
Subscribers can recharge their accounts via service center operators.
Distributed system
The prepay card system allows distributed systems with card roaming to be built, giving your subscribers the ability to recharge their accounts while in roaming.
Blocking
PROTEI Voucher Management System can bar a specific telephone number from accessing the service after several consecutive unsuccessful attempts to enter a PIN code from that number, protecting you from fraud.
Advertising
Additional profit can be generated from placing adverts on cards, and can also be a useful marketing tool for the operator, for example to advertise new services.
Card Status
Information about card usage (transactions made) is recorded automatically in the operator’s billing system.
