My last year of uni I was broke. The previous year the parking passes had red letters, that year purple. That was the only difference. The colour. I traced over all the letters of my previous parking pass with a blue sharpie and parked for free all year.
I do exactly this, and use Keepass2Android on my phone and have nextcloud-KeeWeb installed.
