I’m tired of feeling like a walking data leak every time I step into a crowd.

My paranoia paid off last October. Some guy brushed against me at a concert—classic bump-and-scan move. I’d slipped a Vaultskin NFC blocker in my wallet that morning, that 13.56 MHz jammer creating its tiny 1.2-inch force field of “nope.” My cards stayed silent. His reader got static.

These paper-thin cages need zero power. No charging. No forgetting. Just engineered chaos for anyone trying to skim my life.

But here’s the thing—how many times have you *actually* checked your statements for ghost charges?
