Abstract

The invention relates to the watch type CPU intelligence card with the finger recognition system being added to, base on the watch type radio frequency IC card. When being used to open the induction type door lock, the invented card is the radio frequency induced key board. When benig used to take but, it is an electric ticket. When the card being used to pay charge or draw money no banks, first the card owner put own finger on the surface of the watch for the recognition system to authenticate the finger ID. If the said authentication is passed, the drawing money is allowed so as to protect the safety of the personal deposits. The invented intelligence card is quantitative, also it can distinguishing the processed categories, so making it become convenient 'one card through the city'.

Description

Watch-type smart card for recognizing fingerprint

The invention belongs to the smart card of electronic recognition authentication usefulness, particularly a kind of fingerprint recognition CPU smart card of watch style.

Electronic recognition authentication techniques developed recently is very rapid, extensively be penetrated into every field, teller's card that depositing and drawing in bank is used, peony-card in the traffic administration, the mess card of dining room, campus dining usefulness, employee's recording attendance card on and off duty, open the key card of gate inhibition or electronic lock, the employed member card of supermarket or parking and public place of entertainment ... or the like, usually widely used is various forms PVC card, as magnetic stripe card, IC-card, induction type IC card, also there is part non-contact induction type IC-card to bring into use the form of jewelry formula encapsulation, as watch style wrist strap card, the keyfob of animal cartoon moulding, chest card, plastics keyfob or the like, and by the development of Computer Networking, can realize a card multipotency greatly, a card is except that being used for the many places financial consumption, can also be used to open the door and store personal medical information, just normal " all-purpose card " said, but in their use, must be by means of password (plain code or private mark), can not be qualitative, if leave password, only suitable one starting key, who holds it all can be used, fingerprint identification technology then can be accomplished one yard of a people, strict qualitative can't being decrypted duplicated, also saved the trouble of cipher memory and input, but it can't quantitatively be directly used in consumption again, in addition, though the card volume of making of PVC is very little, carry yet light, but when being to use it, take in the Chang Yaocong pocket and take out, also forget easily when more changing one's clothes and lose, use the smart card of watch style just not have this disadvantage, for example Hong Kong " eight reach logical " that use, be used for the charging of having a prescription priced of public transport for the IC carrier with the wrist-watch, be equivalent to electronic ticket, very convenient, but this watch style radio-frequency card can be quantitative, can not be qualitative, who holds its use of all can getting on or off the bus, structurally its inductive coil and IC chip all are the medial surfaces that is installed in the rear back cover of accutron housing in addition, suffer very closely with movement and button cell, there is quite big interference the metal parts on the movement and the metal surface of button cell to the magnetic line of force of inductive coil, the distance of induction is accepted in influence greatly, and to pry open the bonnet of table when changing the electronic watch battery, the distortion of plastic rear cover when prying open often will injure inductive coil or IC chip, cause inefficacy, at the above-mentioned drawback that present various smart cards exist in the use, the inventor thinks and is necessary to be improved.

The objective of the invention is to solve present consumption-orientation smart card problem quantitatively and qualitatively, comprehensive by smart card techniques and fingerprint identification technology, overcome the general intelligence card for preventing password and be stolen or duplicating, the problem that needs frequent conscious conversion to change, based on the watch style radio-frequency (RF) IC card, add fingerprint recognition system, the radio frequency IC watch card of simple function is developed into multi-function smart card, make radio frequency induction IC watch card develop into convenience-for-people " city one table is logical ".

The object of the present invention is achieved like this, on the wrist-watch carrier of an overall plastic system, position at suitable dial plate, laying have the digital lcd display screen the fingerprint collecting plate as dial plate, watch face has two functions, a function is to make the fingerprint collecting plate, another function is the table that clocks of liquid crystal display, the demonstration of time can be direct digital display, also can be that imitative pointer-type shows, in the table circle periphery on dial plate upper strata, insert a radio frequency induction receiving coil, in the rear back cover of whole table body lower floor, load onto jumbo button cell, the energy as system, middle table cover part insert is gone into fingerprint recognition CPU and peripheral control circuit, the watch style smart card that constitute this moment, when being used for the induction type door lock and opening, it is exactly the radio frequency induction key card, when being used for public transit system and having a prescription priced by bus, it is exactly an electronic ticket, when doing wholesale consumption or making a draft of money, at first with oneself finger by on dial plate, doing the fingerprint identification, by after can handle the formality of draft, if losing by other people, integral body chooses, because fingerprint recognition can not be passed through, system can not make a response, thereby has guaranteed the safety of individual deposit.

Further set forth structure example of the present invention below in conjunction with accompanying drawing

Accompanying drawing 1 is a system block diagram

1. fingerprint collecting plates, 2. radio frequency induction receiving coils, 3. fingerprint recognition CPU among the figure

4. peripheral control circuit (storer and logic control circuit)

Whole electrical system is made up of four parts, fingerprint recognition CPU has constituted smart card for recognizing fingerprint when combining with the fingerprint recognition collection plate, the authentication of control financial consumption, individual medical treatment or insurance system, when fingerprint recognition CPU combines with the radio frequency induction coil, just constitute a noncontact induced intelligent card, can be used for the opening the door of gate inhibition or radio frequency induction lock, electronic ticket, dining room meal card, the small amount consumption such as clock of stopping, clock partly is used to control the liquid crystal display of dial plate time, and peripheral control circuit is used for logic control and storage.

Accompanying drawing 2 is outside drawings of this smart card

The 1. tamper-proof collection mirror 2. radio frequency induction aerial coils with liquid crystal display among the figure

3. plastic casing 4. operates control buttons

Accompanying drawing 3 is that figure is partly cutd open in the side of this smart card

The 1. tamper-proof collection mirror 2. radio frequency induction aerial coils that have a liquid crystal display among the figure

3. plastic casing 4. is operated control knobs

Watch style fingerprint recognition CPU smart card, the liquid crystal time showing on its dial plate is done two kinds Layout can be selected imitative pointer time showing or with the number of week calendar by owner's hobby The word formula shows that the radio frequency induction aerial coil is installed in the table circle periphery of table body front, at table The periphery of circle is provided with the sky that radio frequency induction coil two ends link to each other with the fingerprint recognition cpu chip Line interface, middle table cover part insert fingerprint recognition CPU and peripheral control circuit, should The peripheral control circuit is made up of memory and logic control circuit, in the bonnet of table body lower floor Depositing a jumbo button cell, showing external limit and set up a Menu key and several Function key is used for menu and shows or blanking, the time of clock adjust, clock setting and gate inhibition, The functions such as consumption, the access of wholesale finance, medical authentication are switched. Every activation one action 6-10 second changes resting state thereafter automatically over to, to save energy consumption.
