Description
Technical field
The utility model relates to a kind of IC smart card, and particularly a kind of Non-contact IC smart card belongs to the radio-based electronic devices field.
Background technology
Due to developing rapidly of electronic equipment, the consumption of IC smart card has related to every field, phonecard, and bank card and medical insurance card etc. are consumed because of the IC smart card and have all been brought facility to user both sides, thereby become a kind of consumption pattern of being rooted in the hearts of the people.Traditional IC smart card generally includes the PVC card of an IC intelligent chip and a standard, and the surface of this PVC card is provided with a groove, and described IC intelligent chip just is embedded in this groove, and the surface of IC intelligent chip need be exposed to the surface of PVC card.During use, be the IC smart card to be inserted the inside of card reader, contact to carry out the signal transmission by IC intelligent chip and the read write line of the inside of card reader, complete the read-write of IC smart card, record consumption information.Above-mentioned IC smart card is the IC smart card of contact, although brought convenience for people's life, because of the imperfection on its structure and principle, has following shortcoming:
(1) owing to being Mechanical Contact between above-mentioned IC smart card and read write line, often because plug-in card, the insertion of non-card foreign object, dust or greasy dirt cause the loose contact of IC smart card and read write line roughly;
(2) be exposed to the surface of PVC card because of the IC intelligent chip, easily cause come off, the crooked damage, or the problem such as electrostatic breakdown, confidentiality and reliability are low.
(3) need insert the inside of card reader due to the IC smart card, use inconvenience, efficient is lower; (4) sequence number of contactless card is unique, and manufacturing firm solidifies this sequence number before product export, can not change again.
(4) sequence number of contactless card is unique, and manufacturing firm solidifies this sequence number before product export, can not change again.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Non-contact IC smart card, adopts contactless mode to work between itself and read write line, efficient is high, not fragile, confidentiality and reliability high.
The utility model is achieved in that a kind of Non-contact IC smart card, comprise an IC intelligent chip and PVC card, it is characterized in that: this Non-contact IC smart card also comprises an aerial coil, described PVC card is formed by upper PVC layer and the encapsulation of lower PVC layer, and described IC intelligent chip and described aerial coil are encapsulated between PVC layer and lower PVC layer after connecting.
Described IC intelligent chip is RF Card Microchip, includes to encrypt to control and the communication logic circuit.
The inside surface of described upper PVC layer or lower PVC layer is provided with groove corresponding to the position of described IC intelligent chip and aerial coil, and the shape of this groove is similar to described IC intelligent chip and aerial coil.
This Non-contact IC smart card also comprises a decorative surface layer, and this decorative surface layer comprises upper epidermis and lower top layer, and described upper epidermis and lower top layer stick on respectively on the outside surface of described upper PVC layer and lower PVC layer.
The utility model Non-contact IC smart card has following advantage:
(1) reliability is high: between Non-contact IC smart card and read write line, machinery-free contacts, avoided because the various faults that produce are read and write in contact, in addition, the Non-contact IC smart card surface is without exposed IC intelligent chip, need not worry that the IC intelligent chip comes off, electrostatic breakdown, the problems such as crooked damage, both be convenient to card print, improved again the dependability of card.
(2) easy to operate, efficient is high: because this Non-contact IC smart card is non-contact communication, read write line just can operate card in the 10CM scope, thus needn't the plug card, very convenient user uses.When using, contactless card do not have directivity, card can skim in any direction the read write line surface, but both complete operations, and this has improved the speed of each use greatly.
(3) anti-collision: quick anti-collision mechanism is arranged in this Non-contact IC smart card, can prevent from occurring between the IC intelligent cards data and disturb, therefore, read write line can " simultaneously " be processed many Non-contact IC smart cards, this has improved the concurrency of using, and virtually improves system works speed.
(4) can be suitable for multiple application: the memory construction characteristics of contact card make its one card for multiple uses, can apply to different system, password and access consideration that the user is can be according to different application settings different.
(5) encryption performance is good: Non-contact IC smart card is by the IC intelligent chip, and induction antenna forms, and is sealed in fully in a standard PVC card, without exposed parts.The read-write process of Non-contact IC smart card is usually by completing read-write operation by radiowave between non-contact type IC smart card and read write line.The sequence number of this Non-contact IC smart card is unique, and manufacturing firm solidifies this sequence number before product export, can not change again.Adopt bi-directional verification mechanism between contactless card and read write line.It is the legitimacy of read write line checking IC smart card.The IC smart card is also verified the legitimacy of read write line simultaneously.Contactless be stuck in want before processing and read write line between carry out three authentications mutually, and all data are all encrypted in communication process, in addition, in card, there is operator password and the access consideration of oneself each sector, so confidentiality is high.
