The cash cycle today often is very time-consuming and expensive for banks. Households and retailers pay in their cash using cash payment, automatic teller machines and night safes. The bank has to sort this money, count it and have it brought to the central bank by means of a cash-in-transit company. The central bank checks the money and returns it with a CIT company to the bank for dispensing to customers. The risk of hold-ups, robberies and thefts is therefore also obvious.
