How big a problem is the theft of CIT?
Currency is especially vulnerable when it is moved. Temporarily lacking the security afforded by vaults and alarms, currency is easily misappropriated. The vulnerabilities are even more pronounced in systems that do not make use of armored vehicles or heavily armed guards during the CIT process. In 2008, 500 billion of currency was transported (1.4 billion/day) and there were 1,000 attacks against CIT couriers in the UK (BSIA).
