How does a coin mechanism check the right value of coins inserted into an office vending machine?

Each coin has specific features such as magnetic features, weight, diameter and thickness. The coin mechanism is therefore programmed to “recognise” every coin. But note that every coin mechanism has its limitations. Comparative coin mechanisms can only recognise one type of coin, mechanical coin mechanisms one or two types of coins. Electronic coin mechanisms can recognise up to six different coins thanks to coils which analyse the weight and dimensions of every coin.

When a coin is inserted into the vending machine, the integrated microcontroller compares the signals received with the ones in its database.

Last generation mechanisms use an identification system with image recognition, which works on banknotes for example.
