I haven’t used my PIN number in a couple of years! I remember when you used to have to enter it after so many contactless transactions and now your don’t.
A few months ago, I sat and thought, and realised I couldn’t remember what my PIN number was! Panicked a little and then sat there trying to remember. I eventually remembered by thinking about how my hands would go and what fingers I would touch and that reminded me enough to remember.
Now whenever I start to forget, I do my hand movements. I’ve also added it to my list of passwords cos it’s not a number I want to forget!
