BANKNOTE DOUBLE-NOTE DETECTION METHOD AND DEVICE AND AUTOMATED TERMINAL

摘要

The invention provides a method and device for detecting overlapped banknotes and a self-service terminal. The method for detecting overlapped banknotes comprises: detecting a security thread on a banknote to be detected to obtain security thread characteristics data; determining whether the security thread characteristics data matches a first predetermined condition; and, in the condition that the security thread characteristics data does not match the first predetermined condition, determining that banknotes are overlapped. The detection method and device can easily detect and determine whether banknotes are overlapped and thus improve the accuracy of detection.
