Abstract

PROBLEM TO BE SOLVED: To destroy a used IC card so that this card can not be used afterwards. SOLUTION: The part of an IC chip 2 of a used IC card 1 is mechanically or physically destroyed by punching, cutting, or high voltage impression or the like. Also, when the IC card 1 is destroyed by a mistake, the IC card 1 can be easily re-issued by providing a storage part 5 for allowing other storage devices to store data stored in the IC card 1 prior to the mechanical or physical destruction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card destroyer capable of completely destroying a used IC card.

[0002]

2. Description of the Related Art In recent years, IC cards have been frequently used as represented by non-contact automatic ticket gates and electronic money.

[0003] Such an IC card has the feature that the contents of the memory can be updated and used repeatedly. However, such an IC card is used when the use of a commuter pass is stopped or the transaction of electronic money is stopped. There is a case where the use of the IC card is stopped thereafter.

As described above, when the use of an IC card is stopped, a card company (in the case of a commuter pass, a railway company) is operated to collect the IC card so that the IC card is not illegally used. I have.

[0005]

As described above, a used IC card is operated so as to be collected by a card company, but the collected IC card is updated by updating the memory contents. Since the IC card may be reused, it has been desired to completely stop the function of the collected IC card so that the function of the IC card cannot be reused.

SUMMARY OF THE INVENTION The present invention has been made to meet the above-mentioned demands, and has as its object to use a used IC.
IC that can completely prevent card reuse
An object of the present invention is to provide a card breaking device.

[0007]

In order to achieve the above object, an IC card breaking device according to the present invention provides a mechanical device by punching, cutting, or applying a high voltage to an IC chip portion of a used IC card. Alternatively, it is physically destroyed. Further, prior to mechanical and physical destruction, a storage means for storing data stored in the IC card in another storage device is provided.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an IC according to an embodiment.
It is a schematic structure figure of the destruction device for cards.

[0009] The IC card 1 is a used card that has been used after being discontinued, and contains therein a central configuration of an IC card capable of performing predetermined arithmetic processing, similarly to a known IC card. An IC chip 2 composed of an integrated circuit as an element is embedded.

This IC card 1 is of a connection type,
When a C card is used, the connection terminal 1a is connected to a connection terminal of the card processor by being mounted on a card processor (not shown).

In FIG. 1, P is a punching unit, which has an insertion slot 3 for an IC card 1 and
When the C card 1 is inserted into the insertion slot 3, the connection terminal 1a provided on the IC card 1 is connected to the connection terminal Pa provided on the punching unit P.

In FIG. 1, reference numeral 3 denotes the same reading as a read driver provided in a well-known card processor for reading the contents stored in a memory (not shown) of the IC card 1 obtained via the connection terminal Pa. Department. 4 is a CPU
, And is configured to perform arithmetic processing based on the read data, and to drive the solenoid 6 of the punching unit P when the read data is stored in the storage unit 5.

The punch P 'of the punching unit P is provided so as to be located at the position of the IC chip 2 of the IC card 1 inserted into the insertion slot 3. Therefore, when the solenoid 6 is driven, as shown in FIG. 2, a hole H is made in the chip 2 of the IC card 1, and the function of the IC card 1 is irretrievably destroyed. .

The storage unit 5 stores the destroyed IC card 1
Is stored, and even if the IC card 1 is destroyed by mistake, a new IC card can be issued based on the data stored in the storage unit 5.

FIG. 3 shows that the IC card 1 is destroyed by applying a high voltage to it. That is, the IC card 1 is destroyed by discharging from the high voltage power supply E to the IC chip 2 via the electrode 10.

FIG. 4 shows a piston 20a driven by a driving source such as a hydraulic mechanism (not shown) and the piston 20a.
The IC chip 2 is depressed and broken by a press machine 20 composed of a base 20b having a concave portion into which a is inserted.

FIG. 5 shows an IC card 1 by the cutter 30.
Is cut as shown by C in the figure, and the IC chip 2 is also cut at the same time to break the IC card 1.

FIG. 6 shows a destruction means of the non-contact type IC card 1 'which is used in a non-contact type automatic ticket gate and the like.

The non-contact type IC card 1 'includes a transmitting / receiving unit 40 for exchanging data with a card processor such as a non-contact type automatic ticket gate (not shown), a memory and a CP (not shown).
U, a processing unit 41 for performing predetermined arithmetic processing such as ticket inspection processing, a power supply 42 for driving the non-contact type IC card 1 ', and a destruction circuit 43 which is a characteristic component of the present invention. It is composed of The power supply 42 is
When a circuit for generating a card power supply by receiving a power wave from a card processor is provided, the circuit can be omitted.

The destruction circuit 43 receives the destruction signal on condition that the card processor stores the content stored in the memory of the non-contact type IC card 1 'in the storage unit, and the circuit of the processing unit 41 A high voltage or a reverse voltage can be applied to the power supply to make subsequent use impossible.

Of course, this non-contact type IC card 1 'may be broken by punch holes, presses, or cuts as described above.

[0022]

The destruction device for an IC card according to the present invention comprises:
Punching the IC chip part of the used IC card,
Since the IC card is mechanically or physically destroyed by cutting or application of a high voltage, the used IC card can be destroyed unusably. In addition, when a storage means for storing data stored in the IC card in another storage device is provided prior to mechanical and physical destruction, when the IC card is erroneously destroyed, it is easily reissued. can do.
