Abstract

In a system for transporting bank notes between system terminals in a container for valuables, referred to as a cassette, each cassette is provided with an electronic unit or sealing provision. The electronic unit includes a counter (131) and a memory (13). The counter (131) registers a new count each time the cassette is opened. The cassettes can be connected both mechanically and electrically to any of the terminals. An electronic unit in a terminal includes a processor (20), a coding unit (21), a decoding unit (22) and a comparator (23). Before disconnecting a cassette from a terminal, the count of the counter (131) is read by the terminal and is encoded with the respective coding unit (21). The coded value corresponding to the count is then stored in the memory (13) of the cassette. At a second terminal the counter setting and its coded value stored in the memory (13) are read. The coded value is decoded by the decoding unit (22) of the second terminal and is compared to the counter setting by the comparator (23). An agreement between the compared values show that the cassette was not opened in transit. Conversely, an opening in transit occurred if the two compared values do not coincide. During transit the memory (13) contains both the counter setting and its coded value. However, these two values can only be compared when the correct decoding algorithm is known.

Claims

1. A system including at least two terminals and at least one cassette for the safe and secure transportation of valuables by means of such cassette from a first terminal to a second terminal of the at least two terminals of the system, said at least one cassette including a processor having a counter and a memory facility, characterized in that the memory facility includes a cassette memory (13) and the counter (131) includes means for establishing counter settings corresponding to the number of times that a cassette is opened;

in that the system comprises means, disposed at the first terminal, for reading a numerical value of a prevailing counter setting, means for coding the numerical value of the prevailing counter setting and means for inserting the coded numerical value into the cassette memory (13); and

in that the system further comprises means, disposed at the second terminal, for reading the coded numerical value from the cassette memory, means for decoding said coded numerical value, and means for comparing the decoded numerical value with the prevailing counter setting of the counter (131).

2. A system for secure transportation of valuables between different terminals, the system including cassettes for containing such valuables in transit between terminals, and at least first and second terminals between which the valuables are to be transported, the system comprising:

in each of such cassettes, a counter, means for advancing the setting of the counter to count the number of times the cassette has been opened, and an electronic memory unit;

in each of the terminals of the system, a processor, a coding unit, a decoding unit, and a comparator circuit; and

means, including means for electrically coupling the counter and the memory unit of the cassette to said processor, said coding unit, said decoding unit and said comparator circuit of any selected one of the terminals, for reading a setting of the counter, for coding such setting of the counter and for storing a coded value of the setting in said memory unit of the cassette prior to disconnection of the cassette from a first of the terminals and transport to a second of the terminals of the system, and for reading the counter setting, reading the coded value stored in the memory unit, decoding the coded value and comparing the decoded value with the counter setting after the cassette has been transported from such first terminal to the second terminal of the system, whereby the counter setting coinciding with the decoded value indicates that the cassette has not been opened in transit between the first and second terminals.

3. A system according to claim 2, wherein the at least first and second terminals of the system are a plurality of terminals, the system comprising in each of the terminals, a processor, a coding unit, a decoding unit, and a comparator circuit, and wherein each of said plurality of terminals are capable of being selected as one of said first and second terminals, the system including with each of said first and second terminals said means for reading a setting of the counter, for coding such setting of the counter and for storing a coded value of the setting in said memory unit of the cassette prior to disconnection of the cassette from the first of the terminals and transport to the second of the terminals of the system, and for reading the counter setting, reading the coded value stored in the memory unit, decoding the coded value and comparing the decoded value with the counter setting after the cassette has been transported from such first terminal to the second terminal of the system.

4. A system according to claim 2, wherein the system comprises a further processor, an electronic lock and a battery, in each such cassette of the system, the further processor being coupled to read information from and write information into said memory unit.
