1. Magnetic analysis and detection of safety line
This is done by a long head in the middle. There are two types: 1. Only detect the presence or absence of the magnetism of the security thread; 2. Detect whether the distribution law of the magnetism of the security thread is the same as that of real banknotes.
It can detect more or less or - the same, and can judge the currency of the denomination according to the law (this detection is better).
2. Fluorescence detection
0 no recognition result
Authenticity detection of currency paper by fluorescence. The paper for currency is specially treated during production. Such paper is the fluorescence detection without fluorescent reaction
Using this feature to detect the authenticity of the currency, the machine with fluorescent reaction will alarm.
3. Magnetic detection
The magnetic head is used to determine the authenticity of the currency by detecting the magnetic properties of the currency. The principle of detection is the same as that of the security wire.
Meaning: the number of magnetic heads does not fully represent whether the machine is good or bad).
4. Infrared detection
Through infrared detection of the infrared value of various denomination currencies, each denomination currency has its own corresponding infrared value.
There are not many machines, and they are in the development stage.
5. Width detection
The width of the currency face is detected by the combination of the code disc and the counting tube.
