Innovations in defense from physical theft: "time locks" in bank branches, where the safes and vaults take a fixed delay on the order of minutes to open, without any way for anyone in the bank to speed this up. This fact is advertised explicitly using stickers and posters around the bank, starting at the entrance. The point is to protect the staff, by making it clear there's nothing that can be achieved by coercion, and to deter robberies by making the criminals wait, vastly increasing their risk of being caught.

(And to add a cherry on top, this is usually not disturbing to actual customers, because they're busy doing usual bullshit paperwork while the safe is unlocking.)
