   IT ONLY CHECKS SIZE AND WEIGHT

   they weigh it and measure it’s diameter.

   compares the dimension and mass of the object to file in its’
   memory. Just like your brain makes comparisions and analysis,
   everyday. How was the fruit by the way?

   Size and weight.

   Now here’s a cool trick.

   One Swaziland Lilangeni coin is EXACTLY the same size and weight as a British one pound coin.

   One Lilangeni is worth GBP £0.07

   go figure.

   (the plural of Lilangeni is Elangeni, the international symbol for the Elangeni is SZL)

   Checks diameter & thickness . The coins also pass a magnet which produces Eddy currents this can then determine the material that the coin is made from.

   As everyone has said, I believe its size and weight. A few years ago when I was in Canada, I found that a British 2p coin works in some $1 machines - Won lots of teddies for less than £1 ; )
