Description

Anti-theft swipe smart card

The present invention provides a technology related to smart cards, especially a smart card that can prevent inductive fraud.

With the progress of the times and the demand for use, the communication transmission mode of smart cards has gradually developed from contact communication transmission to non-contact communication transmission, which is mainly to set up an inductive antenna module in the smart card to perform contactless contact on the chip module. Communication transmission.

The contactless communication transmission technology of the smart card makes the use of the smart card more convenient, diversified and fast. However, such a convenient way of use also increases the risk of use. For example, a caring person can transmit a wireless signal through a special device to detect and steal the wearer's pocket, purse, or other items that often contain smart cards. When skimming, swiping, or embezzling through non-contact communication means, cardholders often cannot detect that the card they are holding is communicating, and it is not easy to prevent them.

The main purpose of the present invention is to provide an anti-theft swiping smart card, so as to prevent users from illegally using the card before being used by others to illegally communicate. To achieve the above objective, the card body of the anti-theft swiping smart card of the present invention at least includes: a chip module; an RFID sensor antenna module electrically connected to the chip module through a connecting circuit; and an anti-theft switch arranged in On the connection circuit, when the connection circuit is not opened, the connection circuit is normally kept open, and when it is opened The connection circuit is turned on. In other words, when the anti-theft swiping smart card of the present invention is placed in a pocket, purse, or in any convenient place where it is not used, it cannot directly communicate with the chip module through any sensing means, so there will be no inductive swiping. Problem: When the user wants to use the anti-theft swiping smart card normally, he can easily operate the anti-theft switch to keep the anti-theft swiping smart card in a state capable of sensing communication.

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

The chip module complies with the contactless smart card ISO/IEC14443 TYPE

A. ISO/IEC14443 TYPE B, ISO/IEC 18092 and JIS X 6319-4/Felica one of the standards, so that the anti-theft smart card can be used in ISO/IEC14443 TYPE A, ISO/IEC14443 TYPE

B, ISO/IEC 18092 and JIS X 6319-4/Felica conform to the standard field for application.

The anti-theft switch may adopt a mechanical switch, such as a sheet touch switch with the effect of automatically popping off when it is released, and has the advantages of simple structure, stable quality, durability, low cost, and convenient operation.

Compared with the prior art, the technical means provided by the present invention can keep the chip module of the anti-theft swiping smart card normally in a disconnected state, regardless of whether it is strayed into the sensing range or maliciously sensed by others, the most direct method can be used. The mechanical blocking method prevents the chip module from conducting non-contact communication with the outside, and achieves the effect of anti-theft brushing. When implemented, the present invention can be applied to smart cards that only have contactless communication transmission, and can also be applied to smart cards that have both contact and contactless communication transmissions. It can prevent contactless communication in smart cards. The function of communication transmission is protected against sensor theft.

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

Please refer to the first and second diagrams, which are schematic diagrams of the structure and circuit diagrams of the preferred embodiment of the present invention. The anti-theft swiping smart card shown in this embodiment can be one that conforms to the definition of an electronic ticket or the EMV specification. The card body 100 is in the form of a sheet and at least contains: a chip module 20, an RFID sensor antenna module 30, and an Connect the circuit 40 and an anti-theft switch 50.

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

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

The anti-theft switch 50 is arranged on the connecting circuit 40. The anti-theft switch 50 is a mechanical switch and has a touch key 51, which normally keeps the connecting circuit 40 open when it is not turned on, and turns the connecting circuit 40 on when it is turned on. In implementation, the touch key 51 can be concealed in the card body 100 or exposed outside the card body 100, so that the user can touch and press the anti-theft switch 50 by indirect contact pressure or direct contact pressure.

In summary, when the anti-theft swipe smart card shown in this embodiment is placed in a pocket, purse, or is not used in any convenient carrying position, it cannot directly communicate with the chip module 20 through any sensing means. Therefore, there will be no problem of being induced to steal the brush; and when the user wants When the anti-theft swipe smart card is used normally, the anti-theft swipe smart card can be kept in a state capable of sensing communication as long as it is easily operated, pinched or pressed on the touch key 51.

The above-mentioned embodiments are examples of several examples suitable for the present invention, and are not intended to limit the present invention. For example, if the same technical means as the present invention is only simple replacement or equal implementation of components, it shall belong to the present invention. The scope of the scope.
