How does RFID blocking actually work?

RFID blocking wallets use a conductive metal layer (typically aluminum or copper) that attenuates 13.56 MHz signals by 30-45 dB, reducing the signal to below card reader detection threshold.

Can RFID wallets block NFC payments?

RFID and NFC both operate at 13.56 MHz, so RFID blocking wallets will block NFC signals as well. This protects against both skimming and accidental NFC card detection.

What is the difference between ISO 14443A and 14443B?

14443A is used for most credit cards (Mastercard, Visa, Amex), while 14443B is used for government ID cards (ePassport, eID). Good RFID wallets should block both frequencies.

RFID blocking that actually works, explained from the material up

RFID and NFC blocking is one of the most common requirements in B2B wallet sourcing, but the technical details decide whether a wallet actually protects a card — not just whether it is marketed as “RFID safe”. This hub collects our sourcing, material and testing guides for RFID-blocking wallets and card holders.

FAQ

RFID & NFC wallets: questions buyers ask before a quote

Short answers to the specification questions that come up most often in this category.

Does an RFID-blocking wallet block phone signals or wireless charging?

A properly built blocker targets the 13.56 MHz band used by contactless cards. It should not affect cellular, Wi-Fi or Bluetooth, because those operate at different frequencies. Wireless charging can be affected if the shielding layer sits between the phone and the charger, which is why RFID inserts are usually placed on the card side, away from the charging coil.

Which frequency do RFID wallets need to block?

Payment cards and passports operate at 13.56 MHz (NFC), while older access cards and some industrial tags use 125 kHz. A wallet sold as RFID blocking should specify 13.56 MHz at minimum. If your market includes building access or hotel keys, ask the factory to test both bands rather than assuming one covers the other.

How do I test whether a sample really blocks RFID?

Use a contactless card and a reader, or a phone with NFC. Place the card inside the wallet and try to read it, then repeat with the card outside as a control. Test several positions, including the open edge and any stitching line, because gaps at seams are where most blockers fail.

What is the minimum order for a custom RFID wallet?

Stock models start at 500 pieces. Light customization such as logo embossing, packaging and label changes starts at 3,000 pieces. Deep customization that needs new tooling or a new internal construction starts at 5,000 pieces. Tooling is quoted separately and depends on the mechanism and material.

Does a metal wallet block RFID without an insert?

A solid metal body blocks most 13.56 MHz reading on its own, which is why many metal card holders are effectively RFID-safe. The risk is the open side and any window or cut-out: if cards can be read through an opening, the wallet still needs a shielding layer or a redesigned enclosure.
