Protects your credit cards, passports, and identity cards from electronic snooping
on January 17, 2014
At first glance, the blocking sleeves aren't too impressive. They're basically thin tyvek envelopes with metallic coatings on the inside. Honestly, at first glance they appear a bit flimsy and don't look like they would stand up to a lot of use, but the credit card sleeves are identical (except for color) to the one that the bank sent my credit card in, and I've been using it for several years, and it's still in good shape. If you're not familiar with it, tyvek is virtually indestructible. You can cut it with scissors, but it's very difficult to tear it or puncture it.
A few years ago, the U.S. General Services Administration (GSA) issued a set of test procedures for evaluating electromagnetically opaque sleeves. For shielding products to be in compliance with their FIPS-201 guidelines, they must meet or exceed this published standard. Shielding products currently evaluated as FIPS-201 compliant are listed on the website of the U.S. CIO’s FIPS-201 Evaluation Program. I checked the current list, and Identity Stronghold shielding sleeves are shown as compliant with the standards with no restrictions. That's proof enough for me.
The Identity Stronghold RFID blocking sleeves are a well made, effective product that meets the established standards for shielding credit cards, passports, and other types of contactless identity cards.
