Abstract:

The method to verify designation of pay telephone with an exchange carrier determines receipt of private pay telephone designation for a private pay telephone (PPT) by an interexchange carrier (IXC). The PPT is programmed with at least one telephone number to an IXC in its storage memory. Using that stored number, the PPT calls on its connected telephone line to the IXC. The PPT determines, without manual intervention, whether a response from the IXC is indicative of a status of receipt of PPT designation for the PPT to receive Dial-Around Compensation by the IXC. The PPT then generates a record and stores the record of the response from the IXC in the storage memory of the PPT. Finally, the PPT communicates the stored record of the response from the IXC to the private pay telephone provider.

Abstract:

A card reader (10) is provided that comprises a forward gate (58) that prevents access to the interior of the card reader (10) by other than standard credit card-sized items. Side retainers (36), (38) and (40) coupled to retaining arms (28) and (30) serve to retain appropriately-sized cards and to eject cards which are not long enough. Rear retainers (54) and (56) serve to maintain appropriately-sized cards in contact with an electrical contact (74) of an electrical contact board (72). A fraud prevention antenna (86) prevents access to the electrical systems within card reader (10) from systems outside of card reader (10). A magnetic stripe reader (22) is included in a card guide (16) to allow card reader (10) to also use magnetic stripe cards.
