Abstract
A telephone for transferring electronic money between money cards has on the top thereof two card inlets of two internal card reader/writers, a display window, a ten-key set used to dial a telephone number or enter an amount of electronic money transaction, telephone function keys, and mode selection keys. It can be operated to transfer electronic money between two money cards inserted in the card inlets, or between a money card inserted in one of the card inlets and another money card linked through the telephone line, thereby enabling person-to-person, person-to-bank, and person-to-retailer transactions based on electronic money.
