    I’ve been in hotels where it’s just detecting that the slot is filled the card doesn’t matter. So you just use the cardboard sleeve the card came in.

    Also been in newer ones that have RFID cards though that are harder but not impossible to spoof

      Oh really? I can’t say I’ve come across the RFID style—basically every hotel I’ve stayed in over the past few years still happily takes my supermarket loyalty card in the power switch thing

      How do you go about the spoofing of those and is it anything simpler than just creating a duplicate card?

        Yeah you’d need cheap RFID blanks and a reader/writer. I do it with my phone easily enough. Just read the hotel card, copy, write to new card
