Parse the word
Chips are just like finger print passwords you can only change them so many times either through lack of options [ten digits] or by continually mutilating the employees to replace the chips. The other problem is a memorised [or not] password isn't open to others just randomly scanning either your chip or the fingerprints so openly left on all objects you touch..
As for Cats mine consistently attempts to open the fish food and eat it.........and just as consistently regurgitates it up on the carpet
