    I have a wallet that’s supposedly shielded and it turned out to be useless. Then I got a jammer card as a marketing gimmick. It doesn’t just shield, it creates interferences. The stronger the EM field the better, to some degree. It actually works flawlessly. At least with my smartphone I can’t read any NFC chip near that card.
