In this paper, the theoretical study and measured technique for the banknote of the reflection light and the transmission light are introduced. After the contrast experiment, the characteristic differences of the true and false banknotes are discovered. The check circuit and check system of the transmission and reflection light were developed with making use of the characteristic difference in the pertinence. The banknote was checked and recognised with the check system. The technology was directly used to doing of finance instrument. The recognizing technology and falsing technology of the banknote will be advanced in the finance instrument. The technique is very applicable.
