Description

Watch-type smart card for recognizing fingerprint

Technical field: the invention belongs to the smart card of electronic recognition authentication usefulness, particularly a kind of smart card for recognizing fingerprint of watch style.

Background technology: 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.

Summary of the invention: 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 aerial 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 micro treatment module 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.
