  • Patent number: 6510804
    Abstract: A marking device in a paper money theft proof system can surely provide a mark to stolen paper money so as to alert the public, and can also be used repeatedly, and thus economically. The marking device has a sensor that detects a shock produced when a paper money container is moved or broken to take paper money contained in the paper money container out of it. A marking device provides a mark to at least a part of the paper money under the control of signals from the sensor, the marking device being constructed so as to partially cut the paper money.
