Since many customers began asking for RFID blocking, I started doing some background research. I found that it’s fairly easy to read unprotected cards using inexpensive equipment or even a smartphone. And that once you have the information, it can be put onto a blank credit card. Losing money is one thing, but RFID is increasingly being built into IDs as well, including licenses from many provinces in Canada as well as several US states.

I’m happy to now introduce RFID blocking Tyvek card sleeves that shield cards which operate at 13.56 MHz and above. They’re lined with aluminum but are still so thin as to take up almost no space. Use them in any wallet to add RFID protection or simply to carry business cards or separate some cards from others.

A few of the card types which are shielded:

  • ID Cards (Canada, Washington, Michigan, New York, and Vermont)
  • Credit cards (PayPass, Blink, sQuid)
  • Building access cards* (HID iClass, HID MIFARE, HID FlexSmart, DESFire)
  • Military cards such as CAC (Common Access Cards)
  • Transit cards (Boston Charlie, DC Metro)
  • Government cards such as TWIC (Transportation Worker Identification Credential)

*Some building access cards are NOT shielded including HID 125 KHz.

I’m interested in hearing from you... are you interested in RFID protection?
