CN202453939U - Non-contact integrated circuit (IC) card - Google Patents

The utility model provides a non-contact integrated circuit (IC) card which comprises an IC chip, an induction coil and a connecting lead, wherein a contactor of the IC chip is welded with one end of the connecting lead, the other end of the connecting lead is welded with a circular copper wire inside the induction coil, the IC chip and the connecting lead are located in the inner side of the induction coil, and the connecting lead is also provided with a magnet switch. The non-contact IC card has the advantages of being simple in structure, convenient to use, capable of avoiding duplication and embezzlement and good in technical performance.

Non-contact IC card

Technical field

The utility model belongs to the radio-frequency card field, especially relates to a kind of non-contact IC card.

Background technology

At present, along with the continuous progress of society science and technology and the development of modernized infotech, the scientific and technological articles for use of various novelties constantly pour in people's the visual field, for people's work and life bring great convenience.But with regard to the current consumption field; Various storage userspersonal informations' the electronic chip such as the card of having a dinner of various bank card, member card, public transport card and students; Just brought huge variation to the current consumption mode of people's life, consumer spending, travel not be used in carries a large amount of cashes on one's body, takes city bus and need not prepare change again; Made things convenient for use, safety also is protected.

Along with the widespread use of IC-card, the safe password protection problem of IC-card seems that important, present IC-card can be divided into contact IC-card and contactless IC card two big classes; Contactless IC card is radio-frequency card, contactless card again, and exempts between the card reader to contact, and is 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.The non-transformer of non-contact IC card own must receive the energy that card reader passes over, and spreads out of with the damping capacity transmission manner, so any one receiver can be read the data in the IC-card, is easy to be replicated and usurps, thereby cause bigger loss to the user.

Summary of the invention

The purpose of the utility model provide a kind of simple in structure, easy to use, avoid being replicated and usurp, have the non-contact IC card of better technical feature.

The technical scheme of the utility model is: non-contact IC card; Comprise IC chip, inductive coil and be connected lead; Weld with an end that connects lead mutually the contact of said IC chip; The other end that connects lead welds with the circular copper wire of inductive coil inside mutually, the IC chip be connected the inboard that lead is positioned at inductive coil, also be provided with a magnetic switch on the said connection lead.

Further, said inductive coil is to be made up of the circular copper wire of inside, middle insulation course, outside self-adhesion glue-line.

Further, be provided with the permanent magnetism sheet metal in the said magnetic switch.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, the permanent magnetism sheet metal is used for the radio circuit of switch read-write equipment, and inductive coil is used for sending or reception information; The IC chip is used for handling and canned data; During use, non-contact IC card is pressed close to read-write equipment, activate the radio circuit in the read-write equipment through magnetic switch; Then radio frequency being sticked into row handles; Automatically close radio circuit after handling, thereby reduce the power of read-write equipment greatly, easy to operate simple.
