Description
Technical field
The utility model relates to a kind of device of wireless communication technology field, specifically is a kind of film smart card.
Background technology
Smart card is a kind of plastic clip that is embedded with microchip, and its substrate mostly is the PVC material now, and contact intelligent card and contact type intelligent card are arranged usually.Surface of contact is generally metal material, and the contact generally has 8 (C1C2C3C4C5C6C7C8, C4 and C8 are designed to keep in the future use), and its general thickness is the 2-3 millimeter.Contactless smart card includes a noncontact coil and is used for communicating by letter with the external read card apparatus, and the general size size meets the standard of ISO7816.The payable type smart card of present stage noncontact is nothing to be surprised at, and the manufacture craft of the smart card of making paper moulds is also multifarious, regardless of known to the function of the smart card of making paper moulds, its be inconvenient to carry with manufacture craft single outmoded be the problem of an outwardness all the time.
Find through retrieval prior art, Chinese patent literature CN201374093, put down in writing a kind of " electronic payment card ", this technology comprises processor, the communication interface and the storage unit that are connected with described processor, described communication interface comprises the SWP interface, can be connected with mobile communication terminal, pay by mails, increase user's convenience so that be applicable to remote online.But this technology thickness is big, is inconvenient to carry, and the member of whole utility model is many, forms complicated.
The utility model content
The utility model is at the prior art above shortcomings, a kind of film smart card is provided, its thickness is less than 1 millimeter, area is less than 32mm*48mm, can be placed in the middle of the bonnet of portable terminal and the battery and do not influence the bonnet of portable terminal and the gap degree between the battery, and simple structure uses, inhale the ripple layer by increasing, further strengthen anti-interference, prop up the problem that the smart card of making paper moulds is inconvenient to carry in the prior art thereby effectively solve.
The utility model is achieved through the following technical solutions, the utility model comprises: antenna loops, intelligent card chip, electric capacity, suction ripple layer and basalis, wherein: antenna loops, intelligent card chip and electric capacity are encapsulated in respectively to be inhaled between ripple layer and the basalis, the winding of antenna loops uniform ring places around the inside of film and the two ends of antenna loops and the antenna end of intelligent card chip and the two ends of electric capacity are in parallel, and intelligent card chip and electric capacity are positioned at antenna loops.
The both sides correspondence that is positioned at intelligent card chip on the described basalis is provided with several hard contacts.
Described electric capacity is rectangular structure, is specially the electrolysis patch capacitor of 2mm*1.25mm*0.5mm, in order to regulate electric property.
Described suction ripple layer is the suction ripple layer that the anti-electromagnetic interference (EMI) material of thickness 0.1～0.7mm is made, in order to filter extraneous undesired signal.
Described antenna loops is square structure or circular configuration, in order to the induction outer signals.
The utility model can be realized the non-payment that connects on the basis that does not rely on any external device, its design concept novelty, and the integral thickness of film smart card can be placed between the bonnet and battery of portable terminal only smaller or equal to 1 millimeter, is easy to carry very much.
