I can foresee a time in the not too distant future where the referee will have access to instant replay via multiple camera angles at the touch of a button or vocal command. Either via a wrist screen or glasses, adjudicators at each side of the pitch would monitor and notify the referee of potential rule breeches and send him (or her) a clip for confirmation, the referee would then award the relevant colour card for the transgression.
As it is, too much is left on the eyes of one man at ground level. We have the technology, let's bring it in, in the interest of fair play. Would also help to cut down on this stupid fake diving nonsense too.
