The currency detector is a machine that verifies the authenticity of banknotes and counts the number of banknotes. Due to the large scale of cash circulation and heavy cash processing at the bank teller counter, the money counter has become an indispensable device.
Integrating counting and counterfeiting, with the development of printing technology, copy technology and electronic scanning technology, the level of counterfeit banknote manufacturing is getting higher and higher, and the counterfeit counterfeiting performance must be continuously improved. According to the different trajectories of banknotes, the banknote counters are divided into horizontal and vertical banknote counters. The counterfeit identification methods usually include three methods: fluorescence recognition, magnetic analysis, and infrared penetration. Portable currency detectors are further divided into portable desktop laser currency detectors and portable handheld laser currency detectors.
