Signal-shielding fabric with low surface resistance and high blocking performance — ideal for protecting electronics, RFID cards and personal data. Key features Surface resistance: < 0.05 Ω for reliable conductivity. Shielding performance: 70–90 dB at a high blocking rate. Size: Each piece measures 39" x 44" (100 x 110 cm). Width 44" (110 cm), length 39" (100 cm). Multiple-piece orders: If you order more than one piece and need continuous/adjacent lengths, please specify this in the seller notes. Otherwise each piece will be shipped as 39" x 44". Optimal protection when the item is fully enclosed. Why customers need this Protects sensitive electronics and RFID-enabled items from unauthorized scanning, signal interception and interference. Helps reduce the risk of data theft from credit cards, passports, phones and other devices by providing a physical shielding layer. Works as a practical material for creating privacy- and safety-focused products without changing device functionality. Function, compatibility and performance Function: Conductive shielding fabric designed to block or attenuate electromagnetic signals. Compatibility: Can be sewn, laminated or fitted into clothing, accessories and device covers. Compatible with consumer sewing and assembly processes. Performance: Low resistance and 70–90 dB shielding provide strong attenuation across applicable frequencies when the shield fully surrounds the item. Typical applications (practical scenarios) RFID protection: Line wallets, card holders and passport covers to prevent unauthorized RFID/NFC reads. Device shielding: Make sleeves or internal linings for phone cases, laptop covers or mainframe housing to reduce interference and protect stored data. Wearables and home use: Integrate into maternity clothing, suits, curtains, blankets, bags or outdoor waist packs to add passive signal protection. Usage notes For best shielding results, the item should be completely enclosed by the fabric. Each piece ships at the stated size unless you request continuous lengths when ordering multiple pieces. Intended as a shielding material; final performance depends on design, seams and how completely the item is enclosed. This fabric provides a practical, fabric-based solution for improving privacy and signal protection in clothing, accessories and device enclosures while retaining ease of fabrication and strong shielding performance.
