Description

Anti-theft smart card

This creation is about the technology of smart cards, especially a smart card that can prevent theft of sensors.

With the development of the times and the demand for use, the communication transmission mode of smart cards has gradually developed from contact communication transmission to contactless communication transmission. It mainly sets an inductive antenna module in the smart card to contactlessly the chip module. Communication transmission.

The smart card's non-contact communication transmission technology makes the use of smart cards more convenient, diversified, and fast. However, such a convenient way of use also increases the risk of use. For example, a caring person can send a wireless signal through a special device to perform inductive stealing on the pockets, purses or other items of smart cards often placed on the carrier. When recording, stealing, or embezzling through non-contact communication methods, cardholders often cannot notice that the card being held is communicating, which is not easy to prevent.

The main purpose of this creation is to provide an anti-theft smart card to prevent users from illegally communicating and stealing before they use the card. In order to achieve the above purpose, the card body of the anti-theft smart card of this creation includes at least: a chip module; an RFID induction antenna module electrically connected to the chip module through a connection circuit; and an anti-theft switch, It is arranged on the connection circuit, and keeps the connection circuit normally open when it is not turned on, and turns on the connection circuit when it is turned on. In other words, when this creative anti-theft brush smart card is placed in a pocket, purse, or in any convenient portable position and is not used, it cannot directly communicate with the chip module by any sensing means, so it will not be stolen by induction. Problem; when the user wants to use the anti-theft smart card normally, as long as the anti-theft switch is easily operated, the anti-theft smart card can be maintained in a state capable of sensing communication.

The anti-theft smart card is in compliance with the definition of the electronic ticket or the EMV specification, so that the anti-theft smart card is applied in a form that conforms to the definition of the electronic ticket or the EMV specification.

The chip module complies with one of the standards of contactless smart cards ISO / IEC14443 TYPE A, ISO / IEC14443 TYPE B, ISO / IEC 18092 and JIS X 6319-4 / Felica, so that anti-theft smart cards can be used in ISO / IEC14443 TYPE A, ISO / IEC14443 TYPE B, ISO / IEC 18092 and JIS X 6319-4 / Felica comply with the standard field.

The anti-theft switch can be a mechanical switch, such as a thin-film touch switch with an automatic pop-up and power-off effect when released. It has many advantages such as simple structure, stable quality, durability, low cost, and convenient operation.

Compared with the previous technology, the technical means provided by this creation can keep the chip module of the anti-theft smart card normally in an open state. No matter whether it is accidentally inducted into the sensing range or maliciously stolen by others, the most direct The mechanical blocking method prevents the chip module from performing non-contact communication to the outside, and achieves the effect of anti-theft brush. When implemented, this creation can be applied to smart cards with contactless communication transmission in addition to smart cards with both contact and contactless communication transmission, which can prevent contactless The function of communication transmission is protected by anti-theft brush.

The first figure is a schematic diagram of the structure of the best embodiment of the creation; the second figure is the schematic diagram of the circuit of the best embodiment of the creation.

Please refer to the first diagram and the second diagram, which are a schematic diagram of a structure and a schematic diagram of a preferred embodiment of the present invention. The anti-theft smart card shown in this embodiment may be one that complies with the definition of an electronic ticket or the EMV specification. The card body 100 is in a thin sheet shape and contains at least: a chip module 20, an RFID induction antenna module 30, a The connection circuit 40 and an anti-theft switch 50.

The chip module 20 complies with one of the standards of contactless smart cards ISO / IEC14443 TYPE A, ISO / IEC14443 TYPE B, ISO / IEC 18092, and JIS X 6319-4 / Felica.

The RFID induction antenna module 30 is electrically connected to the chip module 20 through the connection circuit 40.

An anti-theft switch 50 is disposed on the connection circuit 40. The anti-theft switch 50 is a mechanical switch and has a touch key 51, which keeps the connection circuit 40 normally open when it is not turned on, and turns on the connection circuit 40 when it is turned on. During implementation, the touch key 51 can be concealed inside the card body 100 or exposed outside the card body 100, so that the user can perform a touch operation on the anti-theft switch 50 by means of indirect contact pressure or direct contact pressure.

In summary, when the anti-theft brush smart card shown in this embodiment is placed in a pocket, purse, or in any convenient portable position and is not used, it is impossible to directly communicate with the chip module 20 through any sensing method. Therefore, the problem of being stolen by sensors will not occur. When the anti-theft smart card is normally used, as long as it is easily operated, held or touched on the touch key 51, the anti-theft smart card can be maintained in a state capable of sensing communication.

The above-mentioned implementations are examples of some embodiments suitable for the creation, and are not intended to limit the creation. For example, all the same technical means as the creation are simple replacement or equal implementation of the components, and they all belong to the application for a patent. The scope of the scope.
