The multifunctional electronic display device of band smart card
Technical field
The utility model belongs to intelligent display device, particularly a kind of multifunctional electronic display device with smart card.
Background technology
Smart card: smart card (SmartCard) also be IC-card, and it is a card that has micro integrated circuit chips such as microprocessor and storer, has standard specification.Smart card must be followed a cover standard, and ISO7816 or ISO14443, ISO7816 are the standards of contact reader, and ISO14443 is the standard of non-contact reader-writer.ISO14443 has formulated the standard of the communications protocol standard that is specifically designed to contactless card, the transmitting-receiving and the identification of definition noncontact mode data.Smart card can be divided into memory-type card and microprocessor card and contact card, non-contact card and double-interface card sheet etc. again according to the difference of loading chip type, the difference of information communication mode.Card is a carrier, and the software of portion is the core within it, and by this software, the external world can carry out data interaction with it.Smart card has replaced software token such as username and password, differentiates the personal identification of accesses network, by importing a PIN code or utilizing the identity of identifying the user based on fingerprint, face or amphiblestroid bio-assay technique.
In the prior art, in the Chinese patent 99212586.3 and 01215586.1, mainly reported the clocking capability of intelligent watch and combined with the IC-card of individual event function.Function singleness; The function of tradition wrist-watch is timing, does not possess functions such as personal information storage, information processing, information interaction usually.Along with Information Technology Development, in identification, the canteen, the supermarket, motorbus, occasions such as residential quarters, more and more contact type intelligent cards that use, the user will benefit from the convenience of noncontact interface, need not during as fast transaction card is inserted in the read write line; Supplier also will benefit from the easy system integration of non-contact reader system, solid, not fragile, and the low cost of safeguarding that brings thus.Office user, domestic consumer and mobile subscriber have also promoted the strong growth to small and exquisite, safe portable IC-card demand to the sharp increase of various online and Connection Service demands.But the card that existing smart card form mainly is a plastic cement on the market, volume is less mostly, damage easily or lose, function is also single, like this, it is not very convenient that the user carries, use the project of smart card service a lot of now, the user gos out and need be with many cards, and is therefore inconvenient in use, lose easily, certainly will influence the safety of user profile like this.Meanwhile, the smart card of Chu Xianing generally can not show inner information in the market, and many insensitive data also can't show, and inconvenient user is from intuitively having gone up the information in the unfreezing.Authentication: uniqueness and the legitimacy of confirming identity.Have quite widely in information such as bank, CA center, intelligent building and security fields and to use.In order to increase work efficiency, strengthen security, require identity identification system recognition user information quickly and accurately usually, identifying user identity.
