Embodiment 1

[0047] In this embodiment, the smart chip of the non-contact smart card is not changed, but the coil structure of the non-contact smart card is changed, and an optical control element is connected in parallel in the middle of the coil of the original non-contact smart card. When the non-contact smart card is in the wallet, Without light, the coils of the contactless smart card would short out, causing the card to stop working. When the contactless smart card is taken out from the wallet to swipe the card, the contactless smart card senses the brightness of the outside, and the coil of the contactless smart card will work normally, thus avoiding the contactless smart card in the wallet instead of touching it. The situation that the information of the type smart card is stolen.

[0048] The specific smart card structure is attached figure 2 As shown, when the light control element is connected in parallel with the coil 1 , the light control element is a light control switch 3 ...

Embodiment 2

[0050] The main difference between the second embodiment and the first embodiment is that, if image 3 As shown, the circuit board layer also includes a tin sheet 4, the tin sheet 4 is integrated with the light control switch 3 and laminated on both ends of the smart chip 2, the integrity of the circuit board layer is better, and the light control element is more compact. It is firm and not easy to fall off and loosen.

Embodiment 3

[0052]In this embodiment, the coil of the non-contact smart card is not changed, the smart chip structure of the non-contact smart card is changed, and a light-controlled short-circuit circuit is added to the original smart chip circuit design of the non-contact smart card. When there is no light, the smart chip of the contactless smart card will short-circuit, which will cause the smart card to stop working. When the contactless smart card is taken out of the wallet to swipe the card, the chip of the contactless smart card senses the brightness of the outside, and the smart chip of the contactless smart card will work normally, thereby avoiding the The information of the contact smart card is stolen and swiped.

[0053] The specific smart card structure is attached image 3 As shown, when the light control element is arranged inside the smart chip, the light control element is a light control short circuit, that is, the light control element is a smart chip 5 integrating lig...

Abstract

The invention discloses a contactless smart card with a security protection function and a security protection method thereof.The contactless smart card comprises a first card face layer, a second card face layer and a circuit board layer embedded between the first card face layer and the second card face layer.The circuit board layer comprises a smart chip and a coil.The smart chip is electrically connected with the coil.The contactless smart card further comprises a light-dependent control element, and the light-dependent control element is connected with the coil in parallel or arranged inside the smart chip.The light-dependent control element is additionally arranged in the coil or the chip of the contactless smart card to smartly control the contactless smart card, information of the smart card is prevented from being stolen, and the security of the smart card is protected.Meanwhile, the thickness of the smart card is not changed, products such as a shielding sleeve and a shielding card are not additionally increased, and the effects of effectively reducing cost and being convenient to operate are achieved.

Description

technical field [0001] The invention relates to a smart card manufacturing technology, in particular to a non-contact smart card with safety protection function and a safety protection method thereof. Background technique [0002] With the rapid development of network information technology, information security has become very important. Traditional magnetic stripes have been gradually replaced by high-security smart cards such as dual-interface CPU smart cards and visual smart cards due to their low technical content, small information storage capacity, and poor security. It replaces and is widely used in payment, ticket and other scenarios. With the application in various fields, the number of dual-interface CPU smart cards has risen rapidly, and criminals in the society have also conducted in-depth research on the cracking technology of contactless smart cards, and the security problems of contactless smart cards have followed. The application security issues of smart c...
