Hi, I am developing a web page in .NET. I have a text box where the users id is entered by scanning their Id card.It should not allow the user to manually enter his Id but it should be able to print the Id in it when the user scans his card. How can I do this?

That said, you don't need the text input control at all. You can simply write the Id using some non-editable element (such as <p>), unless you want to hide all or part of this information, which would be the best idea. You could provide the Id read to the user only on request. Safety first.
