Forms

Data capture forms can be on paper or on screen. They are designed to collect information from human users.
It's important to design forms carefully so that you get exactly the information you need.
A well-designed form uses tick boxes, character boxes and other helpful features to make sure that the information is exactly right for processing.
On-screen forms make use of controls such as drop-down boxes to help get the right information.
