There was a link, I believe on HN, of someone running experiment to measure magnetic field attenuation inside faraday cage wallets. Does anyone happen to have the link?
I remember reading something similar some time ago for RFID/NFC blocking wallets testing. Couldn’t find it with the HN search.
I have one, I know it fairly effectively blocks my bus card, and building swipe card.
