[Structure] When the data of the wireless card 2 is displayed, the data of the wireless card 2 is sent to a wireless card holder and then displayed on a display 6 provided in the wireless card holder.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wireless card holder that displays data stored in a wireless card.

[0002]

[Prior art]

 A wireless card has a built-in memory, etc., and various data is stored in the memory. In addition, since wireless cards are small and convenient to carry, they are used as cash cards and prepaid cards, for example.

[0003]

[Problems to be solved by the device]

 However, the wireless card cannot be replaced because it has a built-in battery that drives the memory. For this reason, since it is necessary to suppress the consumption of the battery, a device such as a numeric keypad or an indicator, which has a large consumption of the battery, is not attached.

Therefore, the data stored in the memory of the wireless card, for example, the data such as the remaining money cannot be seen on the display or the like, which is an obstacle to the use of the prepaid card.

The present invention solves the above-mentioned drawbacks, and an object of the present invention is to provide a wireless card holder for displaying data stored in the memory of the wireless card.

[0006]

[Means for Solving the Problems]

 The wireless card holder of the present invention is formed in a storage part into which at least a part of the wireless card is inserted and a part of the storage part into which the wireless card is inserted. An antenna for receiving, a signal processing unit for processing the data of the wireless card obtained from this antenna, a display for displaying the data processed by this signal processing unit, and a power supply for the signal processing unit and the display. It is composed of solar cells that supply voltage.

[0007]

[Action]

 According to the above configuration, when displaying the data of the wireless card, the data of the wireless card is sent to the wireless card holder and then displayed by the display unit provided in the wireless card holder. In addition, the power supply voltage of the display is supplied from the solar cell provided in the wireless card holder. Therefore, when the data of the wireless card is displayed, the battery of the wireless card is not used, and thus the consumption of the battery can be suppressed even when the data of the wireless card is displayed.

【Example】

 An embodiment of the present invention will be described below with reference to the circuit configuration diagram of FIG. ◎ 10 is a wireless card holder of the present invention, and the wireless card holder 10 has a structure capable of storing a wireless card 20. The wireless card 20 is, for example, a prepaid card and has an antenna, a signal processing unit, a memory and the like built therein.

In addition, the wireless card holder 10 is provided with an antenna 11 that exchanges signals with the wireless card 20 in a non-contact manner. The signal transmitted from the wireless card 20 is received by the antenna 11 and demodulated by the wireless transceiver 12. The data obtained by demodulation is processed by the signal processing unit 13, for example, a microcomputer, and displayed on the display unit 14. When writing data to the wireless card 20, data is input by operating the key device 15, for example, a ten-key pad. The data input from the key device 15 is processed by the signal processing unit 13, modulated by the wireless transceiver 12, and then sent from the antenna 11 to the wireless card 20.

The power supply voltage for the wireless transceiver 12, the signal processing unit 13, the display unit 14, the key device 15 and the like built in the wireless card holder 10 is supplied from the solar cell 16. The solar cell 16 is attached to a part of the wireless card holder 20.

Here, a state in which the wireless card is stored in the wireless card holder will be described with reference to FIG. The supporting unit 1 which constitutes the wireless card holder has a structure in which the entire structure is, for example, folded in two and can be opened both sides. Further, a bag-shaped storage portion 3 for storing the wireless card 2 is formed on one surface which is an inner side in a state where the support portion 1 is closed. It should be noted that the storage section 3 is sized so that all or part of the wireless card 2 can be inserted. In FIG. 1, a state where the wireless card 2 is not stored is shown by a dotted line, and a state where the wireless card 2 is stored is shown by a solid line. In addition, an antenna 4 for transmitting and receiving a signal to and from the stored wireless card 2 is formed in a bag portion that constitutes the storage portion 3. The solar cell 5, the display 6, the wireless transceiver 7, and the key device 8 are formed on the other inner surface.

According to the above configuration, the wireless card 2 can be stored in the storage portion 3, and in that state, the wireless card holder can be stored in a pocket or the like, which is convenient for carrying. In addition, the power supply voltage for devices such as the display 6, the wireless transceiver 7, the key device 8 and the like formed in the wireless card holder is supplied from the solar cell 5 formed in the support portion 1. Therefore, when displaying data of the wireless card 2 or inputting data to the wireless card 2, it is not necessary to use the battery built in the wireless card 2, and the consumption of the battery can be reduced. In addition, since signals are exchanged between the wireless card holder and the wireless card 2 in a non-contact manner, it is not necessary to consider potential separation between the wireless card holder and the wireless card 2. In addition, there is no problem such as contact failure due to electrode contamination when an electrode connecting them is provided, or failure due to potential difference.

In the above embodiment, the case where the wireless card is used as the prepaid card has been described, but the wireless card can also be used as a security card or a wireless commuter pass. Also, if the wireless card holder has a function to output to the printer, the data of the wireless card can be output to the printer.

[0014]

[Effect of device]

 According to the present invention, it is possible to realize a wireless card holder that can display data of a wireless card without using a battery built in the wireless card.
