(1) In the description of the embodiment, the usage section information, the usage period information, the boarding station information, the getting-off station information, the amount of money, information related to the date and time, and the like are set to integer values. In the case of identification information, it is sufficient that identification is possible, and in the case of range designation, it is sufficient that it can be used for designation of a range and determination of whether it is within or outside the range. It may be a numerical value other than an integer value, a station name, a device name, or the like.
(2) An authentication process using elliptical encryption is performed between the memory card and the billing device, but is not limited to this, and other public key encryption (for example, RSA encryption) is used. Also good.

Further, the authentication may be based on a common key cryptosystem with both having a common key, or any other method may be used as long as both can authenticate each other and share a key.
The authentication process need not be mutual authentication, and may be one-way authentication.
That is, the ticket gate device may only authenticate the memory card, or the memory card may only authenticate the ticket gate device.
(3) The user is not limited to using a memory card only when getting on from a station in an available section. (A) After getting on the commuter pass outside the use section, get off within the use section. If (b) get on the commuter pass usage section and get off within the use section, (c) get off the commuter pass use section, board the use section and get off outside the use section In the case of (d) boarding in the use section and getting off in the use section, it can be used.

The memory card uses the boarding station information acquired at the boarding station, and settles the usage fee related to the use of the train outside the usage zone at the getting-off station.
(4) Use of the prepaid function in the memory card is not limited to when the user gets off.
In accordance with the payment system, for example, a predetermined initial fare may be reduced in advance from the remaining amount in the memory card at the time of boarding, and further, the shortage of the fee may be settled at the time of getting off.
(5) The memory card does not need to have both functions of a commuter pass and prepaid, and either one may be used.
