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?
Hi,
how ca we tell which credit cards are included in the protected i.e. PayPass, Blink, etc ?
Thx.
Thanks for the question John – We do actually sell RFID wallets as well: http://www.slimfoldwallet.com/collections/thin-wallet/rfid but some folks like to add these to other wallets they already have. Plus, most of the sleeves out there are made from paper while these Tyvek ones are much stronger.
These sleeves can be purchased anywhere.. Why not have a truly RFID wallet and just integrate the RFID into the wallet instead of having to fumble around with a separate sleeve in the compartment?
@ Ilja – Thanks! Glad you like them. Yes, the material blocks all cards of type ISO 14443A/B. The material has been issued by government agencies such as Canada with their IDs. I’ll see whether a whole wallet would be possible… the material is very expensive.
It’s great that you have been able to line the Tyvek sleeves with aluminium to protect cards from RFID skimming. Is the material thick enough for good protection and/or is this in line with any guidelines, for instance FIPS-201? (see http://en.wikipedia.org/wiki/RFID#Shielding)
I for one would be very interested in Slimfold wallets with this aluminium protection included. Any chance of this happening soon? Keep up the good work!
