Abstract
The utility model relates to a kind of for taking precautions against the card holder that electronic information is stolen, comprise two front covers and be positioned at internal layer (4) between the two, internal layer (4), for holding card, has in the inner side of a front cover and covers layer of metal function film (2); Described metal function film (2) comprises glass layer and metal level, is base cloth, is compounded with metal level at Ji Bushang with glass fibre.The utility model utilizes the electromagnetic principles of the electromagnetic reflection of metal pair, shielding, and at the inside sandwich design metallic diaphragm of clip, reach electromagnetic main energetic and intercepted reflection by metallic diaphragm, the smart card information of protection inside is not stolen.
Description
Art
The utility model belongs to high frequency wireless communication technology field, relates to a kind of for taking precautions against the card holder that electronic information is stolen.
Background technology
Current short distance high frequency wireless communication technology (NearField Communication, being called for short NFC) development is rapidly, can realize carrying out contactless Point-to-Point Data Transmission between electronic equipment to carry out exchanges data. technique is at mass transit card, students' dining hall mess card, a lot of aspect such as prepaid card is well applied, by card near card reader, just the functions such as reading, payment can be completed.If but this technology is by non-normal use, the serious consequence that in card, important information is stolen by lawless person can be caused.If the electronic equipment that short distance high-frequency wireless communication functional application is equipped with in existing report display comprises the distance chip cards such as the smart mobile phone of ordinary people and (comprises IC bank card, have the certificate etc. of store-memory function) distance very near when, just can obtain bulk information in card in non-contacting situation, the important private informations such as a few bit digital in card number end, electronic cash balances, identity card part figure place information, transaction record may be caused for bank card.These important identity cards, bank card, storage card are all generally be placed in wallet or card holder.Therefore in the electronic information of the smart card preventing inside is stolen, necessary protection Design is done to card holder, promote the function of card holder.
Utility model content
The purpose of this utility model is to provide the card holder of a anti-information theft, prevents the important information of held various smart card from being stolen by lawless person's malice.The utility model utilizes the electromagnetic principles of the electromagnetic reflection of metal pair, shielding, and at the inside sandwich design metallic diaphragm of clip, reach electromagnetic main energetic and intercepted reflection by metallic diaphragm, the smart card information of protection inside is not stolen.The technical solution of the utility model is as follows:
A kind of for taking precautions against the card holder that electronic information is stolen, comprise two front covers and be positioned at internal layer (4) between the two, internal layer (4), for holding card, is characterized in that, has cover layer of metal function film (2) in the inner side of a front cover; Described metal function film (2) comprises glass layer and metal level, is base cloth, is compounded with metal level at Ji Bushang with glass fibre.
Preferably; Described metal level can be aluminium foil.
Two described front covers, one is front (6), and another is the back side (5), and metal function film (2) covers the inner side of the back side (5).In addition, also have another kind of embodiment, be also coated with metal function film (2) in the inner side of another front cover.
This kind of design, based on electromagnetic transmission characteristic, adopts and has the metal function film of reflex as the vibrational power flow intercepting electromagnetic wave radio communication to electromagnetic wave.Method is easy, is easy to realize, successful.Effectively can protect the important information in electronic information card, not change function and the configuration design of original product, better improve the function of card holder.
Accompanying drawing explanation
The two-sided intraformational bed in front and back of Fig. 1 card holder is covered with the excellent metal function film of flexility.
The back side intraformational bed of Fig. 2 card holder is covered with the excellent metal function film of flexility.
In figure, 1 upper strata; 2 metal function films; 3 lower floors; 4 internal layers; 5 back sides; 6 fronts
Detailed description of the invention
The utility model proposes two kinds of prevention & protection designs.
The first is for wallet as shown in Figure 1, Ka Bao or card holder etc., these type of article are referred to as card holder by this patent, in the production process of card holder, can be positioned at inside outermost upper strata 1 and lower floor 3 and all be covered with the excellent metal function film 2 of flexility.Because metal has reflection and shielding action for electromagnetic wave, most energy of the radio magnetic wave signal that the electronic equipment with short distance high-frequency wireless communication function sends can by metal function film reflector, thus reach the effect that obstruct wireless signal arrives at card holder internal memory card, play the function that pre-anti-sticking internal information is stolen.
The second stores the card bag etc. of prepaid card for gate inhibition's certificate card bag as shown in Figure 2 or the small amount such as dining room mess card and mass transit card, the front 6 of card bag is normally transparent, the excellent metal function film 2 of flexility can be covered with, the sign explanation of accompanying drawing like this inside the back side 5 of card bag.The same principle, the one side being covered with metal function film has the stolen function of pre-anti-sticking internal information.And block before bag and add when metal function film is convenient to authorization information or pays and short distance high-frequency wireless communication card reader carries out information exchange owing to not covering, complete preset function.These type of article are also referred to as card holder by the utility model.
The metal function film 2 inside covered can adopt the metal-coated fabric that in fiber cloth composition metal plated film or market have.Such as can adopt aluminium foil glass fabric.This kind of product uses unique advanced composite technique, take glass fibre as base cloth, dense film is formed after selecting extraordinary adhesive clad aluminum foil, aluminium foil surface after compound is smooth, reflectivity is high, large to tension in length and breadth, quality is frivolous, overlays on procedure in intraformational bed simple, the effect that the electronic information namely playing prevention card holder internal information card is not stolen, promote the allomeric function of clip, do not affect again the appearance design of clip.
Claims (4)
1. one kind for taking precautions against the card holder that electronic information is stolen, comprise two front covers and be positioned at internal layer (4) between the two, internal layer (4), for holding card, is characterized in that, has cover layer of metal function film (2) in the inner side of a front cover; Described metal function film (2) comprises glass layer and metal level, is base cloth, is compounded with metal level at Ji Bushang with glass fibre.
2. according to claim 1ly it is characterized in that for taking precautions against the card holder that electronic information is stolen, described metal level is aluminium foil.
3. according to claim 1 or 2 any one for taking precautions against the card holder that electronic information is stolen, it is characterized in that, two described front covers, one is front (6), another is the back side (5), and metal function film (2) covers the inner side of the back side (5).
4. according to claim 1 or 2 any one for taking precautions against the card holder that electronic information is stolen, it is characterized in that, be also coated with metal function film (2) in the inner side of another front cover.
