Front end work started and research into Jakob Neilson

I have created the Technician and jobs pages for the front end of the system. I have taken into account the usability design and have been following lecture given by Jakob Neilson.

Link to his lecture to Google of mobile usability futures:

Jakob Nielsen is very keen on the fact that you should test before you launch or as he referred  to "Test it before they de-test it". This has made me very keen on getting a system design completed with basic functionality ready for testing.

(If you would like to login please input "1234" into the input field and it will auto submit)

Problems in Creating Pages:

I wanted the login page to auto submit the form for when a technician swipes their ID card on the scanner. This needed some research into JavaScript so that it would check to see if the input box had numerical input from the scanner.
I managed to sort this issue by checking the input field was equal to 4 charactors, when 4 charactors was met the form would be submitted by the forms submit button. I then used CSS to hide the submit button to keep the design simple to use and not cause confusion for when technicians try to login.
