There are situations where occasional visitors have to be allowed entry through electric gates on an intermittent basis. In order to maintain an increased level of security, CAME offer a "coin-type" "token reader" with re-useable, grooved tokens. The tokens can be given out or sent in advance to users to deposit in the slot on arrival. There many applications for the "token reader" method of switching and it can be used in combination with other forms of gateway switching, e.g. remote controls etc.
