LPT If you need a memory jog for a rarely used pin try this
Many people have credit cards or debit cards that they rarely use but whose use requires a PIN number. I have found that using the last 4 digits of an old phone number for the PIN and writing the first three numbers on the card with a sharpie does the trick. For example if your home phone number as a kid was 848-1773 make the PIN 1773 and write 848 on the card with a sharpie. Works for keypads on garage door openers too.
