Validation and Verification : On-Screen

One verification method is to use on screen prompts. After a user has entered some data it is redisplayed on the screen. The user is prompted to read the data and confirm that it has been entered correctly. If the user has entered any data incorrectly she should respond that the data is inaccurate and retype the incorrect parts.

This method of verification is not very reliable. Many users will not read the information that is redisplayed or check it carefully against the source document. However the method is relatively cheap to use.
