Okay, Mr old fashioned if you like,
it's quite a string of numbers, and transcribing them on a car-park or somesuch has to be checked and double checked. It's an example of how to get it right first time. Good, providing you don't erase it.
Mind you, the older dark numbers don't photograph very well.
Mine has an LED flash, where some are Zenon? It seems reasonably good, but the battery does seem to be needing a charge every day.
