An RFID card is a card with a small chip and antenna that communicates by radio waves when it’s near a reader. You’ll see them used for building access, transit passes, ID badges, and contactless payments (often called NFC).

• Common types: 13.56MHz smart/NFC cards and 125KHz proximity cards.
• On this page: You’ll find blank/rewriteable RFID cards and tags, as well as RFID blocking products (cards, sleeves, and wallets) designed to help reduce unauthorized contactless scans.

Blocking cards don’t store data—they act like a shield to help reduce reads when your wallet is closed. If you need cards for door access or projects, check frequency and chip type to match your system or reader.

RFID blocking cards can help reduce the likelihood of casual, unauthorized contactless reads by creating interference or detuning the signal in your wallet. Actual performance may vary based on how you carry cards and the materials in your wallet.

• Placement matters: Keep the blocker card adjacent to your contactless cards. One per side can help in bifold wallets.
• Materials differ: Leather, metal, and lining thickness can affect how well signals are reduced.
• Orientation counts: Rotating or repositioning the blocker may change results.
• Alternatives: Sleeves can add card-by-card coverage, and some wallets include RFID-shielding layers.

It’s a good idea to test your setup with a contactless reader or access point to see what works best for you.

You can shop a range of RFID items on this page, including blank/rewriteable cards and RFID-blocking accessories for wallets.

• For access/projects: Look for 13.56MHz IC cards or 125KHz options (e.g., T5577/EM4305) that match your reader’s specs.
• For protection: Explore RFID blocking cards, sleeves, and wallets designed to help reduce contactless scans.
• How to choose: Check product details for frequency, chip type, pack size, and compatibility notes.
• Convenience: Order online for delivery or choose pickup if available in your area.

If you’re unsure which frequency you need, review your reader’s documentation or your organization’s requirements before purchasing.

Using a blocking card is simple and doesn’t add much bulk. A few setup tips can help it work more effectively in everyday carry.

1. Placement: Put the blocker next to your contactless cards (credit/debit, ID). In a bifold, consider one blocker per side.
2. Orientation: Try different positions or rotate the card to see what reduces reads best.
3. Daily use: When you want to tap-to-pay or scan an ID, remove that card from the wallet or keep the blocker away from the reader.
4. Wallet type: If your wallet already has RFID lining, you may only need the blocker when the wallet is closed.

Because wallets and setups vary, a quick test at a contactless terminal or access point can help fine-tune placement.

Both options can help, but they work a bit differently. The best choice depends on how you carry and use your cards.

• Blocking card: Protects an area of your wallet, minimal fuss, and no individual sleeves to manage. May require strategic placement and sometimes more than one piece for larger wallets.
• RFID sleeves: Cover each card individually for targeted protection. Adds a bit of thickness and you’ll need to slide the card out to tap or scan.
• RFID wallets: Built-in shielding for convenience, though you may need to present a single card outside the wallet to use it.

Many shoppers combine a blocking card with a sleeve for their most sensitive card. Testing your everyday setup can help you decide.
