  • Patent number: 6122355
    Abstract: A portable pay phone system provides a portable pay phone service that deducts payment for a call from a smart card. The cost for the requested call is determined based on the locations of the portable pay phone and a destination device (called party) and whether the smart card contains enough funds to pay for the call. The portable pay phone system maintains multiple currencies so that any currency contained in the smart card may be used to pay for the call. After the call is connected, the portable pay phone system monitors the call. If the call is completed before the purchased time is expired, any funds that were not expended are redeposited into the smart card. If the purchase time has expired before the call is completed, either the call is terminated or additional funds is debited from the smart card to continue the call. This process continues until either all the funds of the smart card is exhausted or the call is completed.
