An intelligent banknote neutralisation system is a way for banks to protect themselves from people stealing their money. It works by using special sensors that can tell when money is being moved from the bank's vault to somebody's pocket. When it detects that, the system will tell the bank, who can then put a stop to what's happening before it's too late. The whole goal is to help keep the bank and its customers safe, so they don't have to worry about losing their hard-earned money.
