How do they recognize the money you insert?

Coin-Operated Machines. Coin-operated machines hold candy, gum and toys. These are smaller machines that are perfect for positioning by checkout areas and doors. Consider large models with tornado-style dispensing for added interest and enjoyment. Multi-vending machines let you offer up to three different kinds of candy gum to appeal to more.

  • Vending machine has many technical problems such as method of payment, level of security, very heavy structure, and product capacity. Firstly, problems occur with payment method. Coin acceptors often jam up, especially if a bill or other foreign object is inserted into the coin slot.
  • A currency detector or currency validator is a device that determines whether notes or coins are genuine or counterfeit.These devices are used in a wide range of automated machines, such as retail kiosks, supermarket self checkout machines, arcade gaming machines, payphones, launderette washing machines, car park ticket machines, automatic fare collection machines, public transport ticket.

Coin-operated vending machines work by detecting inserted coins through physical and electronic mechanisms. When a coin is inserted into the vendor’s slot, it travels down a specially angled chute. It is angled to generate a set amount of momentum for the travelling coin.

The currency then passes through an electromagnetic field generated by an electromagnet that surrounds the chute, generating an electronic signature according to its chemical composition. If this signature doesn’t match one of the vendor’s computer’s known set of signatures (the different coin values) the coin is not logged by the system, but rejected.

Once through the electromagnetic field, the travelling coin must then cross the reject chute to be accepted by the vendor. To do this, the coin must be travelling at the correct momentum as dictated by the chute, with coins travelling too slowly or quickly stopped with physical barriers. This ensures that only official, known currency is accepted – coins which are too light, too heavy or too big or small are physically stopped, as they do not travel down the chute at the pre-designed speed.

If coins pass both checks, they are logged and accepted by the vending machine and function accordingly; if either check fails, however, the coin is rejected and sent down a second chute for collection.

A SHORT HISTORY OF AMUSEMENTARCADES

VENDING MACHINES
Vending machines aren't really a part of amusement arcades but they have their own curious history.
The ancient Greeks invented the first coin operated vending machine – an urn that dispensed holy water when a coin was inserted, described by Hero of Alexander in his book ‘Pneumatic’. Machines for vending snuff, postcards and even a change machine appeared in the late 18th century, but vending did not become popular until a rash of patents in the 1880s for coin acceptor mechanisms that could distinguish genuine coins from fakes. Since then, an enormous variety of vending machines have been tried.


There was a craze for co-operated bars and cafes in France and Germany in the early 1900s.


There was another craze in the US in the 1950s.
In the UK I vividly remember visiting an automated motorway service station restaurant near Newcastle in the late 1960s. The hot meals were stored cold and came out of the vending machine with a plastic 'key'. You were supposed to put the meal and the key into a microwave cooker. The the service station was very busy, the keys were very brittle, the plates came out extremely hot - the result was pandemonium - crying children, the floor awash with spilt meals, the cookers jammed by broken bits of key and frantic staff producing ordinary food from round the back.

Its hard to think of anything that someone hasn't tried to sell in a vending machine

Its easy to make mechanisms to vend long thin things - but I do worry what the machine in the middle might be vending


I think Japan probably has more vending machines than any other country today.

Including one that vends live lobsters
And these are obviously popular enough in some places to have three in a row.
