With the development of Chinese economy, China has become one of the largest countries in terms of foreign trade in the world, and CNY has also ranked second among the currencies all over the world. Thus, the anti-fake and detection technologies for CNY banknotes are also confronted with new challenges. In this paper, ultraviolet-light currency detector and transmission detector, which are two types of simple but practical electronic instrument, are designed by means of the analysis and research on the different optical properties of genuine and fake CNY banknotes respectively. They can be designed with low cost, have a good effect in detection, and may be widespread easily.
