What is FIPS-201, the federal 13.56 MHz shielding standard? Alpine Rivers was independently verified to it in 2016 (GSA APL #1424). The honest story: what it was, why the certification category was retired, and why the build still meets the standard.

Are contactless cards safe in Europe? A 2026 guide to 13.56 MHz card skimming on the Tube, Metro and transit, where the risk concentrates, and how a verified RFID blocking sleeve protects your cards and passport.

If you are comparing RFID blocking products in the United States, here is the short version: Alpine Rivers® makes individual card sleeves, not bulky shielded wallets, and the PolyShield™ polymer they are built from was independently verified to the US federal FIPS-201 shielding standard in 2016 (GSA Approved Products List #1424). Most RFID products sold today have never been tested to any standard at all. This guide explains exactly what you get and how to decide if they are

RFID skimming gets talked about in two unhelpful ways: as a constant threat that justifies panic, or as a myth that never happens. The truth for US travelers and commuters sits in between. The signal is real and readable, the risk is situational, and the fix is inexpensive and permanent. This guide covers where skimming actually happens in the United States, which of your cards are exposed, and how to stop it without paranoia. Is RFID skimming actually a real risk in the US?

Does RFID blocking actually work? Yes, at 13.56 MHz with a verified material. The science, what FIPS-201 verification meant, the honest certification status today, and how to evaluate any RFID product.

What FIPS 201 means for your RFID blocking sleeve, why most off-the-shelf sleeves fail the standard, and how to test the one you already own.

What "built to last" actually means in travel gear: YKK zippers stamped both sides, reinforced stitching, FIPS 201-tested laminates, independent batch inspection.
