How does the vending machine identify the face value and authenticity of the money invested?
When you throw a coin into the vending machine, how does it determine the size of the coin? How does the banknote determine the denomination? And how is it achieved? Coin detection mainly starts from three aspects: size, material, and weight. Needless to say the size of , the counterfeit currency can't pass this level is just to die. The material detection relies on electromagnetic characteristics. Since the genuine coin uses a special mixed metal material, a specially designed high-frequency oscillator circuit can be used to 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 magnetic impedance of the coin is also related to the size. The size detection is completed in disguise. The comparison of weight is more interesting. The vending machine is designed with a coin'track', and only when the size and density match, the coil can pass through the specified speed range. Otherwise, it's fake~ But one more sentence: I'm really tired of coin fraud. . . If you don't have a large channel, you have to spend a little bit of money. If there is a channel, he will definitely be arrested. . . I don't know how much gross profit each coin needs to make a stable profit? Recognizing denominations and authenticating 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 some of the characteristics to recognize. If the recognition is successful, the authenticity of the banknote will be determined. If you know it, you will know the denomination.
