I was just thinking about this and whether I should get a couple. The sceptic within me doubt their reliability and sees them nothing more than a scam. Like the anti-5g brain scanner tools out there.
Although I noticed a couple of wallets have these built into their design. Supposedly they block frequencies as low as 11.08hz which nfc/contact less transactions use to pass data through terminals.
I know cybertheft is a realistic scenario alas I wonder if this is something I really need to be investing in.
