- an IC card insertion slot is formed at a side face of a body of said IC card reader/writer, a step is formed at said side face where said insertion slot is formed, and a recessed portion recessed from said step is formed on said step at said insertion slot.
- 2. An IC card reader/writer according to claim 1, further comprising a keyboard having ten-keys and function keys arranged on an upper surface of said body of said IC card reader/writer.
- 3. An IC card reader/writer according to claim 1, wherein said upper surface has a curved portion curved upwardly in a direction away from said insertion slot so as to increase a thickness of said body progressively toward the portion thereof far from said insertion slot.
- 4. An IC card reader/writer according to claim 1, wherein said recessed portion guides said IC card into said insertion slot.
- 5. An IC card reader/writer used for interfacing between an IC card and other information systems, said IC card containing at least an integrated circuit capable of writing and reading digital information, wherein
- a keyboard having ten-keys and function keys, and a display section are arranged on an upper surface of said IC card reader/writer;
- an IC card insertion slot is arranged on a side surface of said IC card reader/writer and also at a portion below said keyboard and said display section, said side surface being closer to said keyboard rather than to said display section; and
- wherein said function keys include a key for checking whether or not said IC card containing electronic money is in a locked state.
- 6. An IC card reader/writer according to claim 5, wherein said keyboard keys are soft keys displayed on a liquid crystal display area disposed on said upper surface of said IC card reader/writer, and said display section is located in said liquid crystal display area and constitutes a touch panel.
- 7. An IC card reader/writer according to claim 5, wherein said function keys include a key for displaying a balance of electronic money contained in said IC card.
- 8. An IC card reader/writer according to claim 5, wherein said keyboard is removable from a body of said IC card reader/writer, said keyboard being coupled with said body by infrared light or a radio wave in a case where said keyboard is used in a state removed from said body.
- 9. An IC card reader/writer according to claim 5, wherein said upper surface has a slope, and said display section is disposed on said slope.
- 10. A method of operating an IC card reader/writer used for interfacing between an IC card and other information systems, said IC card containing at least an integrated circuit capable of writing and reading digital information, said method comprising the steps of:
- causing a user to insert an IC card into a card insertion slot of said IC card reader/writer;
- displaying as to whether or not said IC card is in a locked state; and
- causing the user to specify an IC card of another party with which to perform communication of information between said user and said IC card.
- 11. A method of operating an IC card reader/writer according to claim 10, further comprising a step of causing the user to instruct an electronic money transaction to be carried out between said IC cards.
- 12. A method of operating an IC card reader/writer according to claim 10, further comprising the steps of:

- displaying said amount of the electronic money transaction.
- 13. A method of operating an IC card reader/writer according to claim 10, wherein said IC card inserted by said user into said IC card reader/writer is connected with the IC card of said another party via a public telephone line.
- 14. A method of operating an IC card reader/writer according to claim 10, wherein said IC card of said another party is another IC card inserted into said IC card reader/writer.
- 15. A method of operating an IC card reader/writer used for interfacing between an IC card and other information systems, said IC card containing at least an integrated circuit capable of writing and reading digital information, said method comprising the steps of:
- causing a user to insert an IC card into a card insertion slot of said IC card reader/writer;
- instructing a reading out of information stored in said IC card by the user;
- reading out said information stored in said IC card by said IC card reader/writer and transmitting said information to said other information systems; and
- displaying as to whether or not said IC card is in a locked state.
- 16.
