Abstract

PROBLEM TO BE SOLVED: To reduce card operation costs by providing magnetic tapes and rewrite display layers which are located at the same physical relationship from the viewpoint of a reader/writer by changing insertion directions in at least two or more places on the card. SOLUTION: Rewrite display layers 2a and 2b and magnetic stripes 3a and 3b are provided in at least two or more places so as to be the same physical relationship from the viewpoint of a reader/writer by changing insertion directions (1) and (2). First, the magnetic stripe 3a used in the case of the insertion direction (1) is encoded, and a card is operated until the rewrite display layer 2a corresponding to the insertion direction (2) can no longer be used by using the layer 2a corresponding to it. The record information of the stripe 3a corresponding to the direction (1) is encoded to the stripe 3a corresponding to the direction (2). And, the card is continuously operated with the stripe 3b corresponding to the direction (2) and the layer 2b. Thus, durability is upped drastically.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic card having a rewrite display layer suitable for rewriting and displaying the number of service points in accordance with a usage amount or the like. This is a rewrite card technology capable of improving the service life of a plastic card due to the durability of a rewrite display layer or capable of supporting a plurality of applications with one plastic card.

[0002]

2. Description of the Related Art The number of times a rewrite display layer can be repeatedly rewritten, that is, the durability of rewrite display is about 200 to 500 times. Therefore, since the rewrite display layer cannot be used after about 500 times, even if the card itself (including the magnetic tape recording portion) has durability, the durability of the entire card is regulated by the durability of the rewrite display layer. is the current situation. For this reason, the plastic card needs to be frequently replaced depending on the use method (frequency of use) of the card. Therefore, there is a problem in terms of cost, and it is determined that the card cannot be used and may not be adopted.

For example, when trying to introduce a point service with a plastic card having a rewrite display layer on a supermarket, the frequency of use is almost every day.
Since it is less than two years if the number of times is less than 0, when the validity period is set, it becomes one year and the card must be replaced, which increases the cost.

[0004] Further, when there are a plurality of stores in a station building or the like, and, for example, a point service is provided in both a car supply store and a grocery store, it is necessary for customers using both to carry different cards.

Alternatively, the conventional plastic card with a rewritable display layer has one rewritable display layer and one magnetic stripe. In this case, only one application can be supported by one card, and in order to support two or more types of applications, the number of cards must be owned.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the card operating cost by increasing the durability, which is the above-mentioned problem, or by making a single card applicable to a plurality of applications. It is an object.

[0007]

According to the first aspect of the present invention, there is provided a recording medium having at least two positions on a card at the same position as viewed from a reader / writer by changing an insertion direction. A plastic card having a related magnetic tape and a rewritable display layer.

The plastic card according to claim 1, wherein the rewrite display layer is a spot type or a stripe type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings. In order to solve the problem that only about 500 rewrites can be guaranteed due to the durability of the rewrite display layer, the insertion direction is changed as shown in FIG. 1 so that the same positional relationship is seen from the reader / writer. At least two or more rewrite display layers (2a, 2b) and magnetic stripes (3a, 3b) are provided.

The method of using this card is as follows. 1. The magnetic stripe used for the insertion direction (3
a), and using the corresponding rewrite display layer, the rewrite display layer (2) corresponding to the insertion direction.
Operate the card until a) becomes unusable (about 500 times). Rewrite display layer (2
The check until a) becomes unusable is performed by the number of times of processing (the number of rewriting). 2. The recorded information of the magnetic stripe (3a) corresponding to the insertion direction is converted into the magnetic stripe (3b) corresponding to the insertion direction.
Encode to The rewriting program is incorporated in the reader / writer operation software in advance. After the magnetic recording information on the magnetic stripe (3a) is read in the insertion direction, it is erased and the card is ejected. Next, the magnetic stripe (3b) corresponding to the insertion direction is inserted by changing the direction.
Rewrite the read data. As a method of notifying the user of the insertion direction, the information may be recorded in the rewrite display layer. 3. The card is continuously operated with the magnetic stripe (3b) and the rewrite display layer (2b) corresponding to the insertion direction. By doing so, the rewrite display layer is doubled, and the durability is increased to about 1,000 times.

In order to make a single card compatible with a plurality of applications, the concept is the same as above, and separate and independent magnetic stripes corresponding to the insertion direction and rewrite display may be used in each application. .

For example, when two stores provide a point service in a station building or the like, store A encodes a magnetic stripe (3a) used in the insertion direction and uses a rewrite display layer (2a) corresponding to this. Operate as a point application. Store B encodes the magnetic stripe (3b) used in the case of the insertion direction, and operates as a point application using the corresponding rewrite display layer (2b). By operating as described above, one card can support a plurality of applications.

In the above embodiment, two magnetic stripes and two rewrite display layers are provided. However, two or more magnetic stripes and rewrite display layers may be provided in consideration of the specifications and applications of the reader / writer.

[0014]

According to the present invention, the durability of a plastic card, which has been regulated by the durability of the rewrite display layer, is improved. In the case where the card is frequently used, the card expiration date is set longer than before. Possible and lower operating costs.

When a plurality of applications are performed with one card, only one card is required, so that the card cost can be reduced and the user does not need to carry many cards.
