Abstract
The invention relates to the field of electronic materials and new materials and discloses a non-contact integrated circuit card capable of being attached and applied to a metal carrier conveniently. The non-contact integrated circuit card capable of being attached and applied to the metal carrier conveniently is applied to electronic finance field and the intelligent traffic field and is provided with a card body. The non-contact integrated circuit card capable of being attached and applied to the metal carrier conveniently is characterized in that a wave absorbing piece layer adheres to the front side or the back side of the card body, the outer surface of the wave absorbing piece layer is coated with a mucilage glue layer, and a protective paper layer adheres to the outer surface of the mucilage glue layer. According to the non-contact integrated circuit card capable of being attached and applied to the metal carrier conveniently, the problem that a ordinary non-contact integrated circuit card can not be used normally when attached to a metal carrier is solved, the structure is simple, using is convenient, the appearance of the card body is not changed, and the non-contact integrated circuit card can be widely applied to the fields such as the financial payment field, the intelligent traffic field and the logistics field.
Description
Technical field
The present invention relates to microelectronics, field of new, the contactless integrated circuit card of especially a kind of convenience attach applications on metallic carrier.
Background technology
Contactless integrated circuit card, also known as radio-frequency card, is made up of IC chip, induction antenna, and be encapsulated in a PVC card sheet, chip and antenna are without any exposed parts.Be the new technology grown up recent years in the world, REID and IC-card combine with technique are successfully got up by it, solve passive (in card non-transformer) and this difficult problem of contact-free, are quantum jumps of field of electronic devices.Card near read write line surface, completes the read-write operation of data in certain distance scope by the transmission of radiowave.
Its principle of work is as follows:
(1) read write line launches pumping signal (electromagnetic wave of one group of fixed frequency), and digital data modulation is in this radiofrequency signal.
(2) contactless IC card enters in read write line workspace, is encouraged by read write line signal.Under electromagnetic excitation, LC series resonant circuit in card produces resonance, thus makes there has been electric charge in electric capacity in contactless IC chip, when accumulated electric charge reaches 2V, this electric capacity can as power supply for other circuit provide operating voltage, needed for integrated circuit operation in card.(resonance, rectification, filtering, voltage stabilizing).
(3) simultaneously card in circuit demodulation is carried out to the resonance signal received, reduction numerical information, analyzing and processing is carried out to information, judge the order from read write line, as write or revised context in EEPROM, also need 2V voltage to rise to about 15V, with the voltage request of satisfied write EEPROM.
(4), after the order of contactless IC card to read write line processes, response message (being modulated in radiofrequency signal by response message) is launched to read write line.
(5) read write line receives the radiofrequency signal of IC-card and carries out demodulation and restore response message.
But when contactless integrated circuit card is placed on carrier surface with metal material of metal carrier surface or inside (as phone cover shell etc.), due to can inductive loop be produced in respective metal carrier, a large amount of loss electromagnetic field, thus the electromagnetic field launched by card reader causing card to receive is not enough.And contactless integrated circuit card itself is passive, the electromagnetic field that read write line must be relied on to provide provides energy.Therefore, card cannot normal running.
Summary of the invention
Object of the present invention is exactly will solve common contactless integrated circuit card to be attached to the problem that metal carrier surface cannot normally work, and provides the contactless integrated circuit card of a kind of convenience attach applications on metallic carrier.
Concrete scheme of the present invention is: improve for common contactless integrated circuit card, it has card, it is characterized in that: be bonded with in the front of card or the back side and inhale wave plate layer; And scribble adhesive-layer at the outside surface inhaling wave plate layer, adhesive-layer outside surface attachment protection ply of paper.
First remove protection ply of paper when the present invention uses, to the one side attachment of wave plate layer be inhaled on the metal surface again, when therefore using, electromagnetic field will through being transferred to metal surface by absorbing from absorbing material, thus form stable loop, reach the object increasing reading/writing distance, ensure that normal use of the present invention.
Structure structure of the present invention is simple, easy to use, does not change the outward appearance of card, is mainly used as mobile phone sticker, can be widely used in the fields such as financial payment, intelligent transportation, logistics.
Accompanying drawing explanation
Fig. 1 is partial structurtes sectional schematic diagram of the present invention.
In figure: 1-card, 2-inhale wave plate layer, 3-adhesive-layer, 4-protection ply of paper.
Embodiment
See Fig. 1, the present invention has the card 1 of contactless integrated circuit card, particularly: be bonded with in the front of card 1 or the back side and inhale wave plate layer 2; And scribble adhesive-layer 3 at the outside surface inhaling wave plate layer 2, adhesive-layer 3 outside surface attachment protection ply of paper 4.
