    Mythbusters did a bit on that. I seem to recall that unless you’ve got an MRI in your pocket, it should be fine.

      I have a magnetic clip wallet, keeps all my credit cards and stuff in place. doesn’t do anything to my cards, but to hotel room keys? those are much more susceptible o the magnetic field. wallet always erases those mfers. now I just keep my room key in an entirely different pocket/place

      That was probably permanent magnet cards (pre-made credit cards, membership cards, etc) vs re-writable magnetic cards that can be written to with a desktop machine.

        Most hotels use reprogrammable RFID cards, not magnetic cards. Hanlon’s razor dictates negligence or incompetence be assumed first. I think it’s more likely that a hotel employee incorrectly programmed the cards, or just didn’t at all before handing them over.

          They do these days. They used to use magnetic strip. Some low-budget places probably still do. Or even physical keys.

          I vastly prefer the RFID but several of the Homewood Suites and Hampton Inns I stay in each week are still magnetic stripe. I’ve definitely killed one. Used it to unlock my room, but then stuck it in a pocket with my magnetic headphone case when I went to workout
