A parking area control and management system employs a card reader, which reads identification information from a card commonly carried by a person, such as a driver’s license or credit card. The image data acquiring portion is configured to acquire first image data representing a color image. A user may display object-oriented models of the business application representing, for instance, the latest control version, the latest deployed version, and a test version including test modifications. The comparison criteria are then used to determine the state of the element alone or in combination with other comparisons, such as average intensity comparisons. Even an operating system not installed with input tools can perform input operation by invoking an input tool of a local operating system, thereby avoiding repeated installations of input tools for different operating systems, and resolving the issue of large resource usage caused by repetitive installations of input tools.
