1, magnetic identification: check the magnetic printing ink of banknotes all over, and also check the rmb security thread of the fifth edition;
2. Fluorescence inspection: UV light is used to check the quality of banknotes, and an infrared sensor is also used to carry out the detection. If there is a slight change in printing paper, it can be verified to be fake;
3. Through counterfeit currency: According to the characteristics of RMB, coupled with the use of counterfeit currency, the ability to identify various counterfeit currency is improved;
4. Infrared identification and counterfeiting: using an excellent fuzzy identification system, based on the infrared characteristics of banknotes, it can reasonably identify various counterfeit currencies;
5. Multi-spectrometer pseudo: multi-spectrometer lamp source, lens array, optical lens module array, operation and data signal operational amplifier, key-in and output sockets are arranged in a drainage matrix by led particles with different light wavelengths; multi-spectrometer lamp source and The lens array composes the optical path system software, which is used to upload light and focus point refracted light on the rmb on the optical lens array. Use the image analysis function of the optical lens of the multi-spectrometer to identify the authenticity of the banknotes.
