The whole process of vending machine identifying real and fake coins is like this

What is the whole process of the vending machine to identify genuine and fake coins? When using a vending machine to buy something, every time you throw a coin in, how does it determine how much of the coin is? How does the banknote determine the face value? And how is the authenticity of the money identified? Coin detection mainly starts from three aspects: size, material, and weight. The size of the counterfeit currency must be the same as the real currency. If the size is not the same, it will definitely fail the test. In fact, the key point of coin authenticity detection lies in two aspects: material and weight. Material detection relies on electromagnetic characteristics. Since genuine coins use special mixed metal materials, a specially designed high-frequency oscillator circuit can distinguish the magnetic impedance of the material more efficiently. In order to screen out counterfeit coins. In addition, there is a small mystery here. The magnetoresistance of the coin is also related to the size, and the size detection is completed in disguise. The comparison of weight is more interesting. The vending machine has designed a coin 'track'. Only when the size and density match, the coil can pass through the coil in the specified speed range, otherwise it is fake! But one more sentence: genuine coin fraud Too complicated, time-consuming and labor-intensive, if you do not have a large channel, you have to spend a little bit of money. If you have channels, you will definitely be caught. The risk is too high, and you don’t know how much the gross profit of each coin needs to make a stable profit? Vending machine 2. The detection and identification of banknotes and the identification of true and false banknotes can be done at the same time. There are dozens of identifiable features in most domestic and foreign banknotes, including various watermarks, various embedded materials, various pattern details, various concave-convex engravings, and various fluorescent patterns. At the time of recognition, the basic recognition methods include size recognition, pattern recognition, optical recognition, magnetic recognition, etc. Nowadays, currency detectors generally select certain features to recognize. If the recognition is successful, the authenticity of the banknote is If you know it, you will know the denomination. The vending machine is equipped with an advanced real and fake currency identification system, which is safe and reliable.
