Problems solved by technology

When working, the card and the card reading device are not in contact, and the exchange of information is realized by electromagnetic waves, so all the information exchanged is also open and transparent in the space separated by objects. In addition, this kind of card is started by the same electromagnetic wave. Other control switches, although some manufacturers have added some encryption algorithms and other measures when reading and writing data in the card, making it difficult for cardholders to illegally read and write data in the card, but for non-cardholders and cardholders Unknowingly, at a certain distance on the communication channel, eavesdropping and imitating the information in the card, but without any preventive measures

Embodiment approach

[0009] like figure 1 As shown, the non-contact security card of the present invention includes an IC chip 1 and an antenna coil 2, the IC chip 1 is connected to the switch circuit 4 with a connecting wire 3, the switch circuit 4 is a mechanical switch, and a touch switch, controllable Silicon analog switch, voice control switch, vibration switch, photoelectric switch and other circuits. like figure 2 As shown, the present invention can also adopt another kind of implementation mode, the IC chip 1 and the switch circuit 4 are packaged in an integrated circuit module 6, and then the connecting wire 3 is connected with the antenna coil 2 to form a non-contact security card circuit, The circuit is prefabricated in a plastic card 5 to make a non-contact security card.

Abstract

The safety card includes IC chip, antenna coil. The IC chip through the connection wire is connected to the antenna coil. The circuit of the ratio frequency card composed of the IC chip, the connection wire and the antenna coil is encapsulated in the plastic card. The character is that the switch is installed in the connection wire between the IC chip and the antenna coil. Thus, the card owner keeps the decision-making power whether the information contained in the card is allowed to output so as to protecting the private information.

Description

(1) Technical field [0001] The invention relates to an IC card, in particular to a non-contact induction security card. (2) Technical background [0002] Along with the extensive application of IC card, the safety assurance problem of information in the IC card appears all the more important, it is non-contact induction card (also claiming radio frequency card) by it. When working, the card and the card reading device are not in contact, and the exchange of information is realized by electromagnetic waves, so all the information exchanged is also open and transparent in space separated by objects. In addition, this kind of card starts to work by the same electromagnetic wave. Other control switches, although some manufacturers have added some encryption algorithms and other measures when reading and writing data in the card, making it difficult for cardholders to illegally read and write data in the card, but for non-cardholders and cardholders Without knowing it, at a cert...
