Abstract
A pre-paid telecommunications card service in which the card-holder can register the card with a service provider in such a way that the card account becomes associated with the customer's home telephone line. Thereafter, toll calls made over that particular telephone line are automatically charged to the pre-paid card account when a destination telephone number is dialed. The card-holder is therefore freed from having to dial an access number or a card number for each call. The call accounting is carried out in a database with which network switches communicate via SS7 or any other desired data messaging protocol.
