  • I started putting aluminum foil, folded a few times to the size of a typical card, in my wallet, in each flap… a year or two after credit and debit cards started getting RFID chips (the things that let you tap as oppose to swipe), and thus could be scanned and cloned by a guy walking around with a device in their backpack… and one of my cards was cloned this way.

    Everyone called me paranoid.

    Faraday cages block radio signals… RFID works via radio signals.

    Then, that form of cloning cards became more popular, and now, most wallets just feature a bit of metallic weave or layer in them somewhere to prevent that, or the ekster and ridge wallets that just are metal.


  • As far as I know, off the top if my head, there are not any affordable, attach to the tap in your sink type filters that actually filter out microplastics.

    I may be out of date on that, been about 2 years since I last looked at filters… but yeah, afaik, we have no idea how to effectively filter out microplastics from water at an end user standpoint, as we do for other, older, mkre commonly worried about water pollutants.

    … I guess if you fully boiled all your water to the point it is all steam, and then condenses back ti water, in a glass or metal recepticle, that might do something for reducing microplastics, but that is insanely energy and time intensive.
