Garcia-Sayes, "Sensing in Coin Discriminators," 2007 IEEE Sensors Applications Symposium, San Diego, CA, 2007, pp. 1-6. doi: 10.1109/SAS.2007.3743891-4244-0677-310.1109/SAS.2007.374389https://academica-e.unavarra.es/handle/2454/25199This 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.6 p.application/pdfeng© 2007 IEEE.
