This mobile bank was introduced by National Bank of Scotland in 1946. The origins of mobile banking can be traced back to the Second World War, when field cash offices provided all units and individual
officers with the relevant currency of the country in which they were
based and received money from army post offices and officers' shops. These vans were replaced in 1949 and National Bank of Scotland became the Royal Bank of Scotland in 1969 after a series of mergers.
