Each single-space parking meter shall be designed to display, on payment and activation, a signal that indicates legal parking for the duration paid for. Each single-space parking meter shall also be designed:to display continuously the time remaining until the legal parking duration expires; and at the expiration of that time, to display a signal that the legal parking duration has expired. Multi-space metered parking shall operate in accordance with one of the systems described in this subsection. A Pay-and-Display-Receipt System operates through a multi-space meter that, on payment and activation, issues a printed receipt that displays:the amount of parking time purchased; and the date and time at which the paid parking will expire. The meter shall contain clear instructions on how and where the receipt must be displayed on or in the parked vehicle. Failure to display the receipt in the manner specified subjects the parked vehicle to a parking violation the same as if the proper parking fee had not been paid. A Pay-and-Register-Tag System operates through a multi-space meter that, on payment and activation, records and transmits to parking enforcement:the multi-space parking zone in which the vehicle is parked; the license plate number of the vehicle; the amount of parking time purchased; and the date and time at which the paid parking will expire. Failure to register the correct license plate number subjects the parked vehicle to a parking violation the same as if the proper parking fee had not been paid. A Mobile-Payment System allows for payment of multi-space metered parking through one’s own mobile phone or other mobile communication device. On connection with the system and payment, the system records and transmits to parking enforcement:the multi-space parking zone in which the vehicle is parked; the license plate number of the vehicle; the amount of parking time purchased; and the date and time at which the paid parking will expire. Failure to register the correct license plate number subjects the parked vehicle to a parking violation the same as if the proper parking fee had not been paid.
