Aside from the fact that it's obviously wrong so as not to be used, I think it might be a problem putting in the abbreviated date as opposed to just putting the year. With my license, the benefit is that you start with the year, but you still have to look up the date elsewhere on the license. The chance of your eyes playing tricks and misreading the ID are much lower when you have to check two places to come up with the correct date for two reasons: the date itself will stop you, and if it doesn't, the extra time spent looking through the license slows you down long enough to process what you're seeing properly.
