Ke Haosen effects and the pulse signal that produces.As shown in Figure 3.Cheque paper in Fig. 2 is scanned with way of electromagnetic induction,
Amorphous fiber can produce the region of pulse signal, be encoded to " 1 ", not produce the region of pulse signal (such as without amorphous
The region of fiber or amorphous fiber are insufficient to allow testing equipment to produce the region of pulse signal), pulse signal will not be produced, compile
Code is " 0 ".The code pattern of pulse signal is so formed, as shown in Figure 4.As can be seen here, the surface density of amorphous fiber and single fibre
The information capacity of the effect length coding of dimension, i.e., the radical of amorphous fiber is more on every square meter, and the information capacity of coding is bigger.
Before dispatching from the factory, the texture information and magnetic information of cheque paper are encoded, stored, set up network data base, and beaten
It is imprinted on cheque paper.
When using, according to the requirement of false proof rank, following three kinds of ranks can be divided to perform：
1st, general false proof rank, under visible light, we can be scanned by image scanning apparatus such as mobile phones to paper,
Then by software analysis, show that texture information is encoded, compare with the information on paper, confirm the true and false of paper；
2nd, important false proof rank, is scanned using magnetic image scanning sensor to paper, then by software analysis, obtains branching
Reason information is encoded, and is compared with the information on paper, confirms the true and false of paper；
3rd, the false proof rank of highest, while detect texture information and magnetic information, even if with Optical image analysis or magnetic image
Scanning sensor gathers texture information, gathers the information in magnetic information, with paper using way of electromagnetic induction and compares, really
Recognize the true and false of paper.
General false proof rank can meet the false proof requirement of general merchandise.Important false proof rank can prevent simple duplicating
The interference that means are produced to the technological invention.The false proof rank of highest can avoid producing the technological invention using magnetic ink is false proof
Raw interference.
