This paper describes the technologies used in coin
discriminator devices, stressing the improvements and novel
mechanisms introduced by the authors in the past few years as a
result of the cooperation with one leading company in the vending
sector. Emphasis is put on how low-cost sensors are used to
characterize coins (or tokens) and discriminate them from their
counterfeits.
