There are many applications where we want to protect the access to some specific services:
- Amusement ride, games console, surveillance devices, aviation fueling, cloakroom,
voice recorders, cameras, coffee machines, TV remote control, thermostats, washing machines,
and also electric switches for machines in industrial environment.
- Everything related to data processing is stored under PC & network,
excepted phones that are described separately (there are too many of them!).
- When payment is involved, it is stored under money management.
