Improvements The final design will definitely have lights (red and green) and sounds. Also, more information will be viewable, with an area for user comments. The single digit patient IDs will be replaced with SSNs. Drug names will be preferred over numbers as far as showing on the screen. Also, the push buttons will no longer be on the interface once the program is able to receive input from the scanner. They were simply necessary for this programming example.
