@tevruden @patterfloof Had a customer move into a shared office building for a short while. Electronic door entry system. How many combinations did I claim it had to the building management? 2. Clean/dirty marks were on 1, 6, 8, and 9. "there's thousands of combinations" they said. I entered 1968, door opened. I was going to try 1986 otherwise... They agreed they need to clean the pad weekly....
@chloeraccoon @tevruden @patterfloof I had a doctor with one of these and I regularly forgot the code and the dirty/clean keys and no timeout meant I usually got in within a few tries.
