Description

Anti-theft recording and low radio frequency signal isolation sheet for folding wallet

Technical Field

The invention provides an anti-theft recording and low radio frequency signal isolation sheet for a folding wallet, which is inserted into a paper money placing groove in the folding wallet, forms the peripheral protection of the folding wallet through the folding action of the folding wallet, and blocks the electronic chip (RFID) data of various cards in the folding wallet, thereby effectively blocking the transmission and the reception of electronic signals or electromagnetic waves inside and outside the folding wallet and achieving the purpose of preventing skimming.

Background

Radio Frequency Identification (RFID) systems are widely used in daily life, for example: articles such as mobile phones, passports, bank cards, and credit cards. When a user uses a credit card to purchase, the RFID chip of the credit card is only needed to be induced to the signal sensor, the information data of the user can be known through the data identification of the signal sensor, whether the user is a legal user identity or not is judged, and when the judgment is correct or incorrect, the user can directly buy the bill by the credit card, so that the convenience of saving time and changing are achieved.

However, with the expansion of the application layer of RFID, most people nowadays usually have at least one RFID chip sensing card, and for carrying convenience, a plurality of RFID chip sensing cards are often placed in a wallet, and are taken out for use when needed. However, most users often get used to directly place the wallet in the pocket of trousers or the place of taking easily, and when a lawbreaker illegally uses the smart device scanner or the mobile phone with the NFC module to read in the air, the data of the RFID chip sensing card in the wallet will be recorded by the side, so that the personal information in the RFID chip sensing card is stolen, resulting in the identity of the user or the RFID chip sensing card being copied by the lawbreaker, and causing the loss of personal data or financial affairs.

Disclosure of Invention

The invention mainly aims to provide an anti-theft recording and low radio frequency signal isolating sheet for a folding wallet, which is provided with a metal interlayer, wherein the upper surface and the lower surface of the metal interlayer are respectively covered with a protective layer to form an anti-theft recording folding sheet, the anti-theft recording folding sheet is inserted into a paper money placing groove in the folding wallet, the length L1 of the anti-theft recording folding sheet is slightly less than the total folding length L2 of the paper money placing groove, and the width W1 of the anti-theft recording folding sheet is slightly less than the depth D2 of the paper money placing groove, so that the anti-theft recording folding sheet is flatly laid in the paper money placing groove and is positioned at the inner edge of the near outer layer of the folding wallet; therefore, through the folding action of the folding wallet, the periphery protection of the folding wallet is formed, the electronic chip (RFID) data of various cards in the folding wallet are blocked, the transmission and the reception of electronic signals or electromagnetic waves inside and outside the folding wallet are effectively blocked, and the purpose of preventing skimming is achieved.

Another object of the present invention is to provide a low rf signal shielding sheet for a folding wallet, wherein the protective layer is made of wear-resistant and flexible material, so as to protect the folding sheet from being stolen and recorded for a long time, thereby providing a high economic benefit.

It is still another object of the present invention to provide an anti-piracy and low rf signal isolation sheet for a foldable wallet, wherein the thickness of the metal layer is at least 0.3mm, so as to ensure the shielding of the transmission and reception of electronic signals or electromagnetic waves inside and outside the foldable wallet, and to facilitate the folding and bending of the metal layer.

Detailed Description

Referring to fig. 1 to 3, the anti-skimming and low rf signal isolating sheet for folding wallet of the present invention comprises a metal interlayer 10, wherein the upper surface and the lower surface of the metal interlayer 10 are respectively covered with a protective layer 20 to form an anti-skimming folding sheet 100, the anti-skimming folding sheet 100 is inserted into a paper money accommodating slot 301 of a folding wallet 30, the length L1 of the anti-skimming folding sheet 100 is slightly less than the total folding length L2 of the paper money accommodating slot 301, and the width W1 of the anti-skimming folding sheet 100 is slightly less than the depth D2 of the paper money accommodating slot 301.

As described above, the metal interlayer 10 is a sheet of aluminum foil or copper foil, which is a shielding material for blocking (shielding) electromagnetic signal transmission between electronic products, and the shielding effect is more remarkable as the thickness of the metal interlayer 10 is larger, and the shielding effect of the copper foil is larger than that of the aluminum foil.

In the practice of the present invention, the thickness of the metal sandwich layer 10 is preferably 0.3mm to 0.7mm, so as to facilitate the folding of the folding wallet 30 to fold the metal sandwich layer 10.

Furthermore, the protective layer 20 is made of wear-resistant and flexible material, so as to protect the anti-piracy folding sheet 100 for durability, thereby providing higher economic benefit.

Finally, the surface of the protective layer 20 can be printed with at least one pattern or totem 21 for the purpose of merchandise identification to achieve the effect of continuous publicity.

Referring to fig. 3 to 5, in detail, the anti-skimming folding sheet 100 is first laid in the paper money receiving slot 301 and located at the inner edge of the folding wallet 30 near the outer layer, and the folding action of the folding wallet 30 forms the peripheral protection of the folding wallet 30, so as to block the electronic chip (RFID) data of the plurality of cards 40 inside the folding wallet 30, effectively block the transmission and reception of the electronic signals or electromagnetic waves inside and outside the folding wallet 30, and achieve the purpose of preventing skimming.
