Method of positively controlling, storing and transporting banknotes, and a safety cassette and banknote-infeed unit for carrying out the method

Abstract

In a method of providing safe control, storage and transportation of banknotes there is used a closeable cassette (1) provided with locking means, said cassette containing a liquid-dye container (9) which is activated when an attempt is made to force the cassette, thereby to render the banknotes unusable. To prevent a successful robbery against, for example, a store or like place in which banknotes are introduced into the cassette with the aid of a special infeed unit (19, 20), the cassette is constructed so that it can be removably connected to said infeed unit while exposing an infeed opening (16), said infeed unit suitably being provided with a counter means. In conjunction therewith, the associated infeed and packing means of the cassette are inserted into the unit, whereupon banknotes can be fed into the cassette. The cassette, with the banknotes therein, is then released from the infeed unit while closing the infeed opening, whereafter the cassette is transported to a collecting location, e.g. a bank, where an authorized person equipped with a key or a code for the cassette lock (1c) empties the cassette of its contents. The safety function of the cassette includes an electric circuit arranged, when an attempt is made to force the cassette, to ignite a detonator (8) which ruptures the liquid-dye container. The electric safety function is primed automatically when the cassette is closed as it is removed from the infeed unit. The invention also relates to a safety cassette (1) and an infeed unit (19, 20) for carrying out the method.
