The key word is infrastructure. This can mean different things to different people.One meaning is the basic physical and organizational structures and facilities (e.g. buildings, roads, power supplies) needed for the operation of a society or enterprise. A more modern meaning would give a wider definition to encompass the facilities required for the modern electronic age.
Motorway tolls would be a perfect example. Today the barriers and toll collectors can be dispensed with the adoption of pre or post use billing, utilising electronic technology. Clock a numberplate and automatically it cab be placed on a database for all kinds of "nefarious" purposes involving the subsequent filching of money.
