	Generally, it seems like a good idea to keep normal door operation the same once the unlocking system installed. Doors have been slowly engineered over the years and work very well in the case of crowds, fires, etc. Electric strike works well for this, additional actuation also as long as it doesn't '''require''' that it be used to get in our out.

			* Each door has its own microcontroller and reader, stores its own access list ( SD card? )
