Description

A kind of Intelligent Composite IC-card structure

Technical field

The utility model relates to a kind of smart card architecture, relates in particular to a kind of Intelligent Composite IC-card structure.

Background technology

IC-card is the meaning of integrated circuit card, and IC-card is a kind of plastic cards of built-in large scale integrated circuit, and the magnetic card size of the card phone that it is big or small and original is identical.IC-card can be divided into storage card, encrypted card and smart card three classes usually, storage card is the storer that can directly carry out the reading and writing operation to it, encrypted card is to have increased the reading and writing encryption function on the basis of storage card, when encrypted card is operated, must at first check the password in the card, password correctly just can carry out normal running, and smart card is to have microprocessor (CPU), is also referred to as the CPU card simultaneously.

Traditional IC-card is a Contact Type Ic Card, has advantages such as reliability height, security is good, dirigibility is strong; But, when using, all card reader to be injected in the IC-card contact at every turn, use very inconvenience owing to Contact Type Ic Card.The IC-card contact exists easily defective such as pollutes, easy to wear, thereby shortens its serviceable life, damages the Card Reader or the card writer of this type of card even.

Non-contact IC card claims the RFID radio-frequency card again, and the RFID radio-frequency (RF) identification is a kind of contactless automatic identification technology, and it is by the automatic recognition objective object of radiofrequency signal and obtain related data, and identification work need not manual intervention, can work in various rugged surroundings.Compare with Contact Type Ic Card, non-contact IC card need not plug-in card, and is convenient to operation, has advantages such as reliability height, good airproof performance, anti-collision simultaneously.

Also there is following defective in traditional non-contact IC card: when the card curved transitions, card lost efficacy because of the fracture of coil solder joint easily; Be subjected to environmental interference easily and fail in the communication of some occasions; Encryption method is comparatively simple, is easy to crack, and its security is lower.

The utility model content

The technical problems to be solved in the utility model is to overcome technological deficiency recited above, and a kind of Intelligent Composite IC-card structure is provided.

In order to solve technical matters recited above, the utility model is taked following technical scheme:

The utility model provides a kind of Intelligent Composite IC-card structure, include upper strata PVC substrate, the PVC of lower floor substrate, have first printed layers and be laminated with topmost thin film, have second printed layers and be laminated with lower film, also include and pass topmost thin film and be arranged at contact IC chip on the PVC substrate of upper strata, be installed in the sandwich layer between the two-layer PVC substrate at lower floor's PVC substrate outer at upper strata PVC substrate outer; Described sandwich layer is a radio frequency identification component, and radio frequency identification component further includes frequency of operation and reaches the electronic tag that electrically connects with ultra-high frequency antenna at the ultra-high frequency antenna between 870～960MHz.

Described electronic tag is formed by falling packaged chip.

The antenna of described ultra-high frequency antenna for making by etching aluminum foil.

Described contact IC chip embeds and is arranged on the PVC substrate of upper strata.Offer the embedding mounting groove of contact IC chip on the PVC substrate of described upper strata.

The frequency of operation of described ultra-high frequency antenna and electronic tag is 915MHz.

The utility model passes through composite means, with hyper band frequency RFID chip and contact IC chip perfect combination on a standard card, realize the relative merits complementation of contact and non-contact IC card, both overcome Contact Type Ic Card easy pollution, easy to wear, use defective such as inconvenience, also solve non-contact IC card easily because of problems such as the fracture of coil solder joint were lost efficacy, communication is subject to environmental interference, security is lower, prolonged the serviceable life of IC-card effectively.Realize real one card for multiple uses, not only economy but also meet environmental protection concept, practicality is stronger, and function is more, can be widely used in systems such as gate inhibition's control, campus card, animal supervision, cargo tracking, expressway tol lcollection.
