RFID-Blocking Card for Wallets (13.56 MHz NFC Shield, CR80)

What the card does, and what it does not

Contactless bank cards, metro cards and most office access cards work at 13.56 MHz and answer any reader held within a few centimetres. A blocking card placed in the same wallet disturbs that field so the cards beside it stay silent until it is taken out. It does not cover 125 kHz cards, which answer at a different frequency, and it does nothing for UHF tags such as FASTag, which sit on the windshield and are read from metres away. Whether you need one at all depends on the cards you carry and where; the RFID data security guide sets out the actual risk of skimming and cloning before you decide.

Printed for gifting and onboarding

Because it is a plain CR80 card, it prints like our printed ID cards: a logo and message on one side, instructions on the other. Banks and card issuers can add it to the welcome kit of a new contactless card, and companies can hand it out as a practical giveaway with staff cards. Pair it with the blocking sleeve for passports and single cards.

Testing and ordering

Test it with an NFC phone: hold the phone to a contactless card alone, then with the blocking card stacked on it, and the phone should stop reading. Blocking cards follow the consumables rule: minimum order 500 pcs. Request a quote with the quantity and artwork, or see the other card accessories under RFID accessories.
