Induced current reads the true and false of the magnetic characteristic anti-counterfeiting information of safety line by induced current；When safety line material be metal and
When magnetic characteristic anti-counterfeiting information is true, otherwise it is counterfeit money that output test result, which determines that RMB is genuine note,.It is mentioned by two kinds of approach
The high cash inspecting machine false distinguishing ability, reaches field advanced level, popularization and application foreground is preferable.
It should be understood that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
It says, it can be modified or changed according to the above description, and all these modifications and variations all should belong to the appended power of the utility model
The protection scope that benefit requires.
