Currency examination method

Abstract

The invention introduces a currency examination method. The currency examination method includes the steps: utilizing the existing resources and parts of a mobile phone or a flat computer, performing comparison and examination on the counterfeit currency in a currency information data base after reading the information of the examined currency to obtain the real and counterfeit information of the examined currency, and then displaying the real and counterfeit information or performing an acousto-optic alarming. The currency examination method has the advantages of being simple in construction, being easy to implement, being lower in cost, being lighter in weight of product, and being convenient to carry.

Description

technical field [0001] The invention relates to a banknote checking method and belongs to the technical field of banknote anti-counterfeiting. Background technique [0002] Among the existing banknote verification technical solutions, there are mainly the following categories: [0003] 1. Magnetic counterfeiting: detect the distribution of magnetic ink on banknotes, and also detect the security thread; [0004] 2. Fluorescence identification: use ultraviolet light to check the quality of banknotes, and use photoelectric sensors to monitor; [0005] 3. Penetrating anti-counterfeiting: According to the characteristics of RMB, it is equipped with a penetrating anti-counterfeiting mode to increase the ability to identify various counterfeit coins; [0006] 4. Infrared counterfeiting: using advanced fuzzy recognition technology, according to the infrared characteristics of banknotes, it can effectively identify various counterfeit coins; [0007] 5. Multi-spectral counterfeiti...

Problems solved by technology

[0009] The above banknote detection method, so the structure and production of its corresponding products are complicated, the cost is high, and the product weight is relatively large. It is usually used in banknote detectors or ATM deposit and withdrawal machines, and it is not easy to carry and use;

[0010] There is comparative technology 1 having similar features with the present invention, application number 201610445230.8, a banknote verification method based on mobile phones; the feature described in claim 1 includes 4 steps, wherein: a, three databases are established; b , obtain the banknote code information to be checked and upload it to the server; c, the server first compares the code information of the banknote to be checked with the counterfeit banknote code stored in the first database...; the implicit content here is: the database is established in In the server, information transmission needs to be carried out through the network or digital transmission system when checking banknotes; this is not convenient enough in practical applications, and more databases need to be set up; network support must be provided during application, otherwise it will not work; in addition, there is no description of the server The method of providing the network address and the anti-tampering measures, which are easy to be misled by tampering during inspection;

[0011] There is comparative technology 2 that has similar features with the present invention, application number 201510624604.8, a kind of mobile phone banknote checking method, mobile phone equipment and server; The feature described in its claim 1 is: " through the microphone on the described mobile phone equipment to collect knocking After the banknotes to be checked, the sound spectrum information emitted by the vibration of the banknotes to be checked; send the sound spectrum information to the server, and the server will verify the sound spectrum information according to the sound feature information file database”; because The physical stiffness of banknotes is poorly consistent, and its softness and hardness will gradually change during the circulation process, or its stiffness characteristics will be changed due to moisture and pollution, so the extracted vibration sound spectrum will also change, which is different from that stored in the sound feature information archive database. The inherent sound spectrum of banknotes deviates, which is prone to misjudgment, and the sound feature information file database is set in the network server, so it is also necessary to provide network support during the inspection process, which is not convenient and quick enough
