## Summary description

extra digital HB390427 card sleeves (2 pcs) are protective signal-blocking holders designed for ID, access and payment cards. The sleeves prevent RFID/NFC skimming by blocking radio signals while keeping cards slim and wallet-friendly. Use them for travel, daily carry or workplace access to protect personal and financial data from unauthorized reading.

## Long description

Faraday Card Sleeve HB390427 is a set of two shielding sleeves designed to protect ID and bank cards from external electromagnetic signals. The sleeves act like a Faraday cage, preventing unwanted reading or interference with the data stored on contactless cards while remaining passive and not emitting signals or affecting other electronic devices.
Advantages
The sleeves block a range of wireless signals including RFID, Bluetooth, 4G, Wi‑Fi, GPS and GSM, and are lightweight and compact (88 x 57 mm, 3 g each). Supplied as a 2‑piece set, they help prevent remote skimming, accidental data degaussing caused by electromagnetic fields, and interference from mobile phones when a card is kept nearby.
Suitable for
 Protecting contactless ID cards from unauthorized reading
 Shielding bank cards from remote skimming and signal interference
 Storing access cards and transport passes when not in use

 Dimensions: 88 x 57 mm
 Weight: 3 g each
 Signal blocking: RFID, Bluetooth, 4G, Wi‑Fi, GPS, GSM
 Brand: extra digital
 EAN: 9990000390427
How to use
Insert an ID or contactless bank card into the sleeve so the card lies flat inside. Keep the card inside the sleeve when not using it to ensure protection against wireless reading and electromagnetic interference. Remove the card from the sleeve only when you need to present or use it normally.
Usage recommendations
For best results, store cards individually in the sleeves and avoid folding or creasing the sleeve material. Do not attempt to charge or connect cards while they are inside the sleeve; the shielding will prevent normal communication.
