What are Pre-Paid Phone Cards?

A prepaid phone card is a user who buys a calling card at face value and then consumes it. Except for a few smart cards, the value of the card will be used up after the amount stored in the phone card is used up, and cannot be reused.

According to the order that consumers pay and use, phone cards can be divided into two categories, namely phone credit cards and phone prepaid cards (stored value cards), that is, prepaid phone cards.

In the pre-paid mode, the billing system communicates online with the gatekeeper and the gateway.

Prepaid billing data flow

The system is responsible for authorizing the caller and determining the maximum call duration based on the dialed number, user type, balance, and tariff. The advantages of this payment model are:

(1) Pre-paid calling cards can be processed, and calls can be immediately interrupted when the pre-paid amount is exhausted;

(2) The user database is completely maintained by the billing system;

(3) Define new users or update users, and take effect immediately.

In this mode, when the call is established, the gatekeeper and gateway pass the caller's identity and the dialed number to the billing system. The real-time accounting server authorizes the user identity and returns the maximum call duration. When the call ends, the gateway notifies the real-time accounting server and adds the call information to the database. ^[3]
