Banks

are repositories. Generally banks hold (and loan) money, but the term is more widely used, as in databank. Financial banks are themselves massive databanks, the information about the capital they hold becoming equal to or perhaps more important than the money they represent. A bank robbery today is a small thing. Even when a bank has its maximum amount of cash on hand during the Christmas season, a robber can take only a small percentage of the 'real' holdings of the bank. Most of it rests in the bank's expensively fortified database, safe from merely physical robbers. They need security, and will finance technology to provide it.
