Abstract
The utility model relates to an IC card, in particular to a non-contact radio frequency safety IC card. The non-contact safety IC card comprises an IC chip and an antenna coil, the IC chip is connected with the antennal coil by a connecting conductor, a radio frequency IC card circuit composed by an IC chip, a connecting conductor, and an antenna coil is sealed into a plastic card. The utility model is characterized in that the connecting conductor between the IC chip and the antenna coil is provided with a switch which controls the output of the information in the IC chip, and the duplication and the embezzlement of the IC card can be avoided.
Description
(1) technical field
The utility model relates to a kind of IC-card, particularly relates to a kind of contactless safe IC-card.
(2) technical background
Along with the widespread use of IC-card, the safe and secret problem of IC-card seems especially important.IC-card can be divided into Contact Type Ic Card and non-contact IC card two big classes at present.The contact of Contact Type Ic Card exposes on the surface of card, reads the information of IC chip by contacting with card reader; Non-contact IC card is radio-frequency card again, contactless card, with exempt between the card reader to contact, be provided with aerial coil and IC chip in it, when there was suitable electromagnetic wave in the external world, aerial coil coupling energy was the IC chip power supply, when reaching certain voltage, the IC chip is exported the data that are kept in the chip with the damping capacity transmission manner, and at spatial transmission.Because Contact Type Ic Card is with the card reader swap data time, IC-card contacts with card reader, so data, password etc. are difficult for being stolen, and the non-contact IC card non-transformer that is radio-frequency (RF) IC card own, must receive the energy that card reader passes over, spread out of with the damping capacity transmission manner, so any one receiver can be read the data in the IC-card, be easy to be replicated and usurp, thereby cause bigger loss to the user.
(3) summary of the invention
Be replicated the problem of usurping in order to solve non-contact IC card, the utility model provides a kind of contactless safe IC-card.
The technical scheme that adopts is:
Contactless safe IC-card, comprise IC chip and aerial coil, the IC chip is connected with aerial coil by connecting lead, constitute the radio-frequency (RF) IC card circuit, this radio-frequency (RF) IC card circuit is encapsulated in the plastic sheet, and its main points are installing one switches on an electric connection line between IC chip and the aerial coil.
The user presses switch in use, connects to connect lead, and aerial coil coupling energy provides power supply for the IC chip; the IC chip is started working, otherwise IC chip noenergy is not worked; therefore, this switch has played the effect of the data in the protection IC chip, avoids IC-card to be replicated.
(4) description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
(5) embodiment
Contactless safe IC-card comprises IC chip 1 and aerial coil 2.The IC-card chip is outwards drawn and is connected lead 3, wherein a connection lead 3 is connected with an end of aerial coil 2 through a thin film switch 4, another root connects lead 3 and directly is connected with the other end of aerial coil 2, constitute the radio-frequency (RF) IC card circuit, this radio-frequency (RF) IC card circuit gives in a plastic cards 5, makes radio-frequency (RF) IC card.
Claims (1)
1, contactless safe IC-card, comprise IC chip (1), aerial coil (2), IC chip (1) is connected with aerial coil (2) by connecting lead (3), by IC chip (1), connect radio-frequency (RF) IC card circuit package that lead (3) and aerial coil (2) be linked to be in a plastic cards (5), it is characterized in that the lead (3) that is connected between IC chip (1) and aerial coil (2) is gone up and installed a switch (4).
