Product Overview
Custom RFID blocking cards are credit-card-sized passive security shields that protect your contactless payment cards, e-passports, and NFC-enabled IDs from unauthorized scanning and data theft. Based on the Faraday cage principle, each card contains an embedded aluminum composite shielding layer that reflects and absorbs 13.56MHz radio frequency signals, preventing skimming devices from wirelessly reading your card data.
Simply slide one blocking card into your wallet — it shields all contactless cards stacked nearby, without adding noticeable bulk. No batteries, no electronics, no setup required. At just 0.86mm thick and approximately 7 grams, it fits naturally in any wallet card slot. For enhanced durability, a 1.2mm heavy-duty option is also available.
RFIDSU provides complete OEM/ODM service: full-color CMYK printing on both sides with your logo, brand colors, QR code, and usage instructions. Choose from glossy, matte, or frosted lamination finishes. Whether for corporate giveaways, financial institutions, travel agencies, or retail brands, these blocking cards combine data security with brand visibility.
Key Features
Faraday Cage Shielding
Built-in aluminum composite film blocks 13.56MHz NFC signals via electromagnetic shielding. No batteries, no electronics — pure physics-based protection.
One Card Protects All
A single blocking card shields every contactless card in your wallet. Stack it between cards or in any slot — the Faraday effect covers the entire stack.
Credit Card Size
Standard CR80 format (85.5 × 54.0mm) fits any wallet slot. Approximately 7 grams — lighter than most credit cards. Zero added bulk for everyday carry.
Full Custom Printing
CMYK full-color printing on both sides. Your logo, brand message, QR code, or usage guide. Glossy, matte, or frosted lamination finish available.

Frequently Asked Questions
How does a RFID blocking card work?
A RFID blocking card contains an embedded metallic shielding layer (aluminum composite film) that functions as a miniature Faraday cage. When placed in your wallet, the conductive layer reflects and absorbs 13.56MHz radio frequency signals from skimming devices, preventing your contactless cards from receiving enough energy to respond and transmit data.
Does one blocking card protect my entire wallet?
Yes. One RFID blocking card placed in your wallet effectively shields all nearby contactless credit cards, debit cards, and NFC cards stacked within close proximity. For larger wallets or thicker card stacks (8+ cards), you can use two blocking cards — one in front and one behind for complete coverage.
Does the blocking card wear out or need replacing?
No. The aluminum composite shielding film is permanently sealed inside the PVC body with durable lamination. There are no electronic components, no batteries to drain, and no material degradation over time. A RFID blocking card lasts for years of daily wallet use without any performance loss.
Will the blocking card interfere with my cards when I use them normally?
No. The blocking effect only works when the card is inside your wallet alongside your other cards. When you remove a contactless card to tap and pay at a terminal, it works completely normally. The blocking card does not damage, demagnetize, or affect any stored data on your cards.
Can I customize the design with my company branding?
Yes. RFIDSU offers full OEM/ODM custom printing on both sides of the RFID blocking card. You can print your company logo, brand colors, QR code, usage instructions, or any promotional message. We accept AI, PDF, CDR, and PSD design files with 300+ DPI resolution for crisp print quality.
What is the minimum order quantity (MOQ) for custom printed RFID blocking cards?
For blank RFID blocking cards without custom printing, there is no minimum order quantity. For custom-printed cards with your logo and design, the MOQ is 50 pieces. Standard bulk packaging is 200 pcs/box, and we offer free samples for testing before bulk production.
