These tokens are typically used to control access or egress on a parking facility. A token-actuated exit gate coupled with tire- damaging mechanisms on an otherwise open entrance is quite effective in controlling the usage of a parking lot. In the case of a bank parking lot, signage instructs the public that the lot is for bank customers only. Once they have entered, a customer must request an exit token from a teller in the bank. The standard reference catalog for these tokens is "Feisel's Parking Tokens of theWorld" by Duane H. Feisel.
