RFID protection and low frequency signal isolation sheet for folding wallet

Abstract

An RFID protection and low frequency signal isolation sheet for a folding wallet has a metal interlayer. Upper surface and the lower surface of the metal interlayer are covered with protective layers to form an RFID protection folding sheet. The RFID protection folding sheet is inserted into a cash compartment of a folding wallet. The RFID protection folding sheet has a length slightly less than that of the cash compartment. The RFID protection folding sheet has a width slightly less than a depth of the cash compartment. The RFID protection folding sheet is placed into the cash compartment and located at an inner edge close to an outer layer of the folding wallet. By folding the folding wallet, the RFID protection folding sheet forms the peripheral protection of the folding wallet, and the data of the electronic chips (RFID) of cards inside the folding wallet is blocked.

Claims

1. An RFID protection and low frequency signal isolation sheet for a folding wallet, having a metal interlayer, upper and lower surfaces of the metal interlayer being covered with protective layers to form an RFID protection folding sheet, the RFID protection folding sheet being inserted into a cash compartment of a folding wallet, the RFID protection folding sheet having a length slightly less than that of the cash compartment, the RFID protection folding sheet having a width slightly less than a depth of the cash compartment, the RFID protection folding sheet being placed into the cash compartment and located at an inner edge close to an outer layer of the folding wallet.

2. The RFID protection and low frequency signal isolation sheet as claimed in claim 1, wherein the metal interlayer is a sheet of aluminum foil or copper foil.

3. The RFID protection and low frequency signal isolation sheet as claimed in claim 1, wherein the metal interlayer has a thickness of at least 0.3 mm for the folding wallet to fold the metal interlayer easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0015] Referring to FIG. 1 to FIG. 3, the present invention discloses an RFID protection and low frequency signal isolation sheet for a folding wallet, having a metal interlayer 10. The upper surface and the lower surface of the metal interlayer 10 are covered with protective layers 20 to form an RFID protection folding sheet 100. The RFID protection folding sheet 100 is inserted into a cash compartment 301 of a folding wallet 30. The length L1 of the RFID protection folding sheet 100 is slightly less than the length L2 of the cash compartment 301. The width W1 of the RFID protection folding sheet 100 is slightly less than the depth D2 of the cash compartment 301.

[0016] The metal interlayer 10 is a sheet of aluminum foil or copper foil, which is a shielding material to block (shield) the electromagnetic signal transmission between electronic products. The greater the thickness of the metal interlayer 10, the more significant the shielding effect. The shielding effect of the copper foil is better than that of the aluminum foil.

[0017] Preferably, the metal interlayer 10 has a thickness of 0.3-0.7 mm, which is beneficial for the folding wallet 30 to fold the metal interlayer 10 easily.

[0018] Moreover, the protective layers 20 are made of a wear-resistant and flexible material to protect the RFID protection folding sheet 100 for durability. The present invention has high economic benefits.

[0019] The surface of the protective layer 20 may be printed with at least one pattern or totem 21 as a product identification for promotion.

[0020] Referring to FIG. 3 to FIG. 5, in detail, the RFID protection folding sheet 100 is first placed into the cash compartment 301 and located at the inner edge close to the outer layer of the folding wallet 30. By folding the folding wallet 30, the RFID protection folding sheet 100 forms the peripheral protection of the folding wallet 30, and the data of the electronic chips (RFID) of a plurality of cards 40 inside the folding wallet 30 is blocked, thereby effectively blocking the transmission and reception of electronic signals or electromagnetic waves inside and outside the folding wallet 30 to achieve RFID protection.

[0021] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
