來對金融卡帳戶進行收費時，當使用者不慎地讓其錢包或 -5- 200906609 皮夾離此表面太近時，錯誤讀取的可能性增加。同樣地， 當使用一張金融卡來授權收費時，亦可能（故意或意外地） 讀取另一張含智慧晶片的金融卡，因此對單一次購買產生 多於一次的收費。 再者’當考慮到讀取裝置的數目及於此之易受影響度 時’無恥之人可在卡片所有人不確知的情況下讀取於含智 慧晶片的卡片中之敏感訊息。例如，已熟知可在自動櫃員 機（ATM)處使用微型照相機來捕捉輸入PIN碼的人士之影 像。可類似地設置微型讀取器來捕捉已編碼到晶片上的訊 息。特別提供的是，事實上大部分人會面對ATM並打開及 觀看其錢包或皮夾，以便防止在其背後的人士看進其錢包 或皮夾裏面；但是，當吾人想要可靠地保護財產不被窺視 時’不引人注目地設置在ATM上或在其之上且經遠端操作

INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention is broadly directed to an electromagnetically opaque material, and more particularly to an electromagnetic shielding device capable of providing electromagnetic frequency shielding devices, such as radio frequency identification devices (RFID). material. [Prior Art] A system incorporating RFID technology typically includes an RFID "tag" that can be read using any suitable reading device. This strip contains one or more computer crystals ("Smart Wafers") and associated antennas that allow the transmission of messages encoded onto the smart wafer to the reading device. As the smart chips used have become smaller and smaller, the number of devices incorporating RF ID technology (especially with regard to the consumer industry) has increased. Furthermore, because RFID technology is becoming more cost-effective for different business types that need to maintain, distribute, and track inventory, RFID systems are becoming more popular every day. Radio frequency identification technology is also being used in people's tracking and identification. The results are claimed to include RFID tags in passports, ID cards, financial cards and passes so that people can help them more efficiently when they travel through the port. In fact, at the airport, even if you did not use a special financial card to purchase the ticket, the registration of the upcoming flight has now been completed by swiping the credit card at the airline automatic check-in kiosk. Typically, the “efficiency” of RFID systems is accompanied by mistakes, misuse, or even flagrant theft of sensitive information. When a financial card account is charged simply by shaking a card or wand containing a smart chip on the surface of the RFID reading device behind it, when the user accidentally makes his wallet or -5-200906609 When the wallet is too close to the surface, the possibility of erroneous reading increases. Similarly, when a financial card is used to authorize a charge, it is also possible (intentionally or accidentally) to read another financial card containing the smart chip, thus generating more than one charge for a single purchase. Furthermore, when considering the number of reading devices and the degree of vulnerability thereto, the shameless person can read sensitive information in the card containing the smart chip without the knowledge of the card owner. For example, images of people who can use a miniature camera at an automated teller machine (ATM) to capture an incoming PIN code are well known. A micro reader can similarly be provided to capture the information encoded onto the wafer. In particular, most people actually face the ATM and open and watch their wallets or wallets to prevent people behind them from looking into their wallets or wallets; however, when I want to reliably protect the property A read device that is unobtrusively placed on or above the ATM and remotely operated while not being peeped allows direct and easy reading of unmasked encoded messages. What is needed is a device that allows the user to controllably interrupt or prevent the use of RFID technology to read the encoded wafer. SUMMARY OF THE INVENTION In one aspect, the present invention relates to an electromagnetic shielding material. This material includes a first paper film and a conductive layer adhered to the surface of the first paper web. The polymeric film can be adhered to the adjacent surface of the conductive layer. This arrangement defines a layered structure that prevents the reading of the RFID smart chip when it is inserted between the receiving antenna of the RFID smart chip and the transmitting antenna of the RFID signal generator. -6- 200906609 In another aspect, the present invention is directed to an electromagnetic shielding material comprising % -* and a first paper film and having a metallized polymeric film interposed therebetween to form a laminate. Again, when the laminate is inserted between the receiving antenna of the RFID smart chip and the transmitting antenna of the RFID signal generator, it prevents reading of the R F ID smart chip. In another aspect, the present invention relates to an electromagnetic shielding material in the form of a laminate. These laminates are a combination of paper, polymeric film and/or conductive material that prevents the reading of RFID smart wafers. In this regard and in all other aspects of the invention, the paper may be printed using any suitable means including, but not limited to, laser printing devices, ink jet printers, lithographic printers, digital printers, flexographic plates. Printing presses and handwriting tools by hand. In yet another aspect, the present invention relates to a guard that electromagnetically shields an RFID smart wafer. The guard comprises an electromagnetic shielding material having at least one electrically conductive layer and at least one substrate in adjoining configuration. The device can be an envelope, a stent, a sheath, a sleeve, a sheet of paper or card stock, a wall paper or the like. The device can also be incorporated into a carrying device such as a wallet, wallet, handbag, luggage, computer bag, pocket cover or the like. The electromagnetic shielding material prevents reading of the RFID smart chip when the electromagnetic shielding material is inserted between the receiving antenna of the RFID smart chip and the transmitting antenna of the RFID signal generator. In yet another aspect, the present invention relates to a method of electromagnetically shielding an RFID smart wafer. In this method, an electromagnetic masking material comprising at least one electrically conductive material is provided and placed adjacent to the RFID smart chip, preferably between the RFID smart chip and the transmit antenna 200906609 of the RFID signal generator. By doing so, the electromagnetic shielding material can interrupt, block or generate the Rf ID signal to the RFID antenna of the receiving antenna of the R F ID smart chip. One advantage of the present invention is that it has been encoded into a private message that can be placed via an RFID (e.g., 'RFID Smart Wafer), which cannot be read without the approval of the owner. In particular, the electromagnetic shielding smart chip will interfere with the transmission and reception of the plane wave field propagation signal, and the reader can find out that the information contained in the smart chip is invalid, so that the portable RFID chip can be inserted. A person such as a 'passport, ID card, credit card, transit card or Chuantong card or the like) can confidently feel the ability to read the information it has encoded on the device. Passwords or messages cannot be read without explicit permission. In a specific example where the smart wafer is located in a small device (e.g., a form) that can be carried by a person, the electromagnetic shielding material of the present invention can be in the form of a clip, a sleeve, or a device product capable of holding an RFID smart wafer. In addition, or in the alternative, the electromagnetic shielding material is in the form and remains adjacent to the smart wafer. In any particular example, the paper clip, sleeve or the like may be printed, embossed, cut & punctured and/or folded in any configuration. This paper can also be coated. Providing the light weight nature of paper, most of the paper is suitable for use in the invention. In the case of electromagnetic materials, used in envelopes or other document support, the envelopes of other document supports can be cut into a transparent or mouth to allow the document to be viewed manually or without touch. Offset from the signal, so the read of the private message material adjacent is enough to be invalid. If the device is used for the purpose of permitting the device, the document is the envelope, and the similar paper may be a thin film, coated, colored, cut or uncoated. 200906609 In the specific example where the smart wafer is located in a relatively large or not easily mobile device, the electromagnetic shielding material of the present invention can be used to shield the package or even the entire room. In particular, computer hard drives, computer media, and other types of electronic devices' packages can be lined, coated, or otherwise incorporated into electromagnetic shielding materials. This package includes, but is not limited to, computer cases, disc cases, cases, and the like. Other packages may include drums, tote bags, tray packaging devices, cargo containers, and the like. This electromagnetic shielding material can even be a wallpaper or insulation or other paper form that can be used to line the ceiling and floor. [Embodiment] DETAILED DESCRIPTION OF THE INVENTION A specific example of an electromagnetic shielding material is shown generally at 10'. The electromagnetic shielding material 10 is a four-layer laminated material comprising a first paper film 12, a polymeric film 14, a conductive layer 16, and a second paper film 18. The surface of each of the first paper film 12, the polymer film 14, the conductive layer 16, and the second paper film 18 adjacent to each other is adhered to each other using the adhesive 20. Both the first paper film 12 and the second paper film 18 comprise a fibrous web material. In one embodiment, the membrane material is formulated with, but is not limited to, one or more natural fibers (such as cotton), synthetic fibers, and/or recycled fibers. As such, such membrane materials include a sputum suitable to provide at least some of the desired opacity. The colorant may be added to one or both of the first paper film 12 and the second paper film 18 as desired. The paper may also be synthetic or human paper or the like. This paper can be coated or uncoated. Polymer film 14 includes any suitable polymeric material. Typical materials that can be used for the polymeric film 14 include, but are not limited to, polylactic acid (polylactic acid (p〇ly -9-200906609 lactide)) (a polymer made from corn dextrose and known) It is PL A), polyesters, polypropylenes, combinations of the foregoing, and the like. The material of the paper film and the polymeric film is described in U.S. Patent No. 6,673,465 to the name of the entire disclosure of U.S. Patent No. 6,926,. Conductive layer 16 comprises any suitable electrically conductive material. In one embodiment, the conductive layer 16 comprises a metal foil, wherein the thickness of the foil is adapted to cause radio signal interruption, interference or impedance adjacent thereto. The metal foil also imparts some degree of opacity to the ί electromagnetic shielding material. In this embodiment, the metal used is aluminum, although other metals (e.g., copper, silver, nickel, and the like in the form of elements or alloys) are also within the scope of the invention. The use of a metal in the form of a foil allows the electromagnetic shielding material 10 to better accommodate the folded configuration. In another embodiment, conductive layer 16 can comprise metal particles that have been deposited onto one or more of polymeric film 14 and second paper film 18. The metal particles may be aluminum (e.g., elemental aluminum), aluminum alloy or aluminum-containing compound 'or they may contain other metals (e.g., copper, silver, nickel, and the like). In still another embodiment, the conductive layer 16 can be a metal woven or non-woven strand. In still another embodiment, conductive layer 16 can comprise a non-metallic material such as carbon, a carbon-loaded host material, graphite, combinations of the foregoing, and the like. Carbon nanotubes in single wall or double wall form can also be used. In a specific example in which a carbon nanotube is used as the conductive layer 16, the carbon nanotube can be deposited using any suitable technique such as chemical vapor deposition or the like to obtain a precisely controlled thickness of the conductive layer. -10- 200906609 In still another embodiment, the adhesive 20 can conduct itself. In this particular example, the adhesive includes a suitable electrically conductive material that is mixed therein. Such elements include, but are not limited to, metals in the form of granules, powders, granules, beads, combinations of the foregoing, and the like. The metal may be aluminum (e.g., 'elemental aluminum), aluminum alloy or aluminum-containing compound, or they may be other metals (e.g., 'copper, silver, nickel, and the like). The adhesive 20 used to adhere the first paper film 12, the polymer film 14, the conductive layer 16, and the second paper film 18 to a laminate form may be a solid adhesive agent of 100%. The invention is not limited to this point of view, as other adhesives are also within the scope of the invention. In particular, the adhesive 20 can be solvent based, water based, hot melt, UV radiation hardenable, electron beam hardenable, combinations of the foregoing, and the like. When 100% of the solid adhesive is used in laminating the first paper film 12, the polymer film 14, the conductive layer 16, and the second paper film 18, 'destructive bond is generated between the paper film and the polymer film. . Destructive bonding means that after the paper film and the polymeric film are hardened, under the T stripping adhesion test, I will not allow I to separate the paper film from the polymeric film while the paper remains intact. When a solid binder of 1% is used, the adhesive is a low-temperature (flowable at room temperature of about 100 °F) two-component adhesive. Alternatively, the adhesive can be a one-component adhesive that is hot (gel at room temperature, heated to permit flow). Alternatively, the adhesive may be selected depending on the adhesive permeability and holdout of the paper film to be used (the ability to retain the adhesive). Generally, if the paper is concerned with the permeability and resistance of the paper, a hot-temperature adhesive is used; when the permeability and resistance are less controversial, a low-temperature adhesive is used. When using 1%% of the 200906609 solid adhesive, the 檩-layering technique is usually used to achieve the build-up. ί Referring now to Figure 2, another specific example of an electromagnetic shielding material is shown generally at 11 inches. The electromagnetic shielding material 11 is a laminated material including the first paper film 112, the polymer film 114, the conductive material 116, and the second paper film U8. The first paper film 112 and the polymer film 114 are disposed adjacent to each other and adhere to each other using the adhesive 12〇. The conductive material 116 penetrates or otherwise penetrates into the polymeric film I" to define a metallized polymeric film that removes the need to adhere the conductive material to the polymeric film. The second paper film i is used ("adhesive" 8 adheres to the polymeric film 1 1 4 (into the conductive material 丨丨 6). In the electromagnetic shielding material 110, both the first paper film 112 and the second paper film ii8 comprise a fibrous film material (similar to the previous specific example) And the polymeric film 141 is a polyester, polypropylene or the like having sufficient dimensional stability, shrinking characteristics to 'balance' the ability to adhere to the paper film material and heat resistance. However, in the electromagnetic shielding material 110 The electrically conductive material 110 comprises particles of suitable electrically conductive material in the form of a powder, such as aluminum, copper, silver, nickel, alloys thereof or the like. Non-metallic materials such as carbon, carbon-loaded matrix materials, graphite, carbon may also be used. a nanotube, a combination of the foregoing, a combination of the foregoing with a metal, and the like. In this embodiment, the conductive material shawl 116 may be uniformly dispersed throughout the polymeric film II4 (as shown in FIG. 3), or it may be Along the aggregation One surface of the film is concentrated (as shown in Fig. 4, now referring to Fig. 5, another specific example of an electromagnetic shielding material is generally shown at 210.
