I recently got a new card and remembered the PIN spatially. After a few times of typing it in I realised that, though I was typing the digits of the new PIN, I was subvocalising the digits of my old PIN. It was a really odd sensation.

Having said that, I would recognise both PINs as both a string of digits and as a spatial sequence... so that would probably just be another attack vector.

I trained myself to do this on purpose; subvocalising a different number. If I'm drugged out in a hospital bed and someone asks for my CC PIN, I want them to get an incorrect number.

Well that took a turn... Do you also by chance drink poison every day to build immunity for when that vicious lad taps your drink?

[Deestan]

Yes - If he tries to poison me with caffeine, I'm pretty safe.

I'm not genuinely worried about being robbed of my PIN, though. I just found the mental challenge interesting.

Wow. I used to think that I was rigorous about security...
