Biddeford residents voted in 2014 to ban the use of parking meters "in the greater downtown area," but since then, the City Council has voted to install "parking kiosks" instead, claiming meters and kiosks aren't the same thing.
The City of Portland has been slowly replacing the old fashioned parking meters with new meter boxes that not only take coins, but credit cards. With new technology comes a new way of doing things, and that allows you to do three things you couldn't with an old style meter.
