This reminds me of my casino days. For slot machines each has several seals and the firmware and OS were checked each time anything was changed. We used a machine from a company called Kobetron for the EEPROMS but later the check was the OS on a disk. Seals were two layer foil with TAMPER when pulled off or a plastic tab that had a wire embedded in it.
