Parking meters are devices used to collect fees from drivers who park their vehicles in designated areas. They are typically found on city streets and in parking lots, allowing local governments to manage parking space availability and encourage turnover. Drivers pay for parking by inserting coins, using credit cards, or through mobile apps, depending on the meter's technology. These meters help ensure that parking spaces are used efficiently and can prevent overcrowding. The revenue generated from parking fees often goes towards maintaining public infrastructure, such as roads, sidewalks, and public transportation systems, benefiting the community as a whole.
