      If you've cloned the passport, you have a physical document.

      Hmm, but cloning a passport isn't like cloning a magstripe, or are you saying it is?

      It's exactly like cloning a magstripe, depending on the security built into the passport

      Exactly? Doesn't the passport have a smart chip built in? I believe it does, and in which case it would not be exactly like cloning a magstripe.

      Most passports have a RFID chip as well as an optical band, no magstripes. But it’s the physical features of a passport that are difficult to clone. If you have a blank passport and the correct printing machines you can forge one. I don’t see why you would be cloning one.

      Right, that's my thought as well. I'm confused why someone would pay for valid passport dumps if nobody can verify them anyway? Maybe there is some way to verify them I'm not aware of?

      They can be verified if they have a signed chip - but the only place they actually ever get verified is at certain gov border crossings. Every other use of the passports does not involve verification - just visible inspection of photo/name

      That makes sense - but the chip cannot be cloned either, so doesn't that mean that the numbers are not that useful, because you can just forge any name/number combination?

      I guess that's not surprising 😆 but still, unless it's querying a database, then you could still have used any number as the passport number, right? I guess I'm trying to get at why someone would pay to know the real number is 135349 and not just use 123456.

          If it's signed and verified, then you can't forge it even with the proper equipment. If it's not signed or not verified, then just use whatever number for free, no need to pay for a real looking number?
