AWOL:
Get a big pad of paper, with rows and columns ruled on it.
Every time someone takes a tagged object, strike out the old location for the tag number, and write down the new location.
If you like, have the secretary transfer the contents of the paper onto a database.
That is one way to do but I don't want to do paper work. I want it to automatically send its location to a database and find out in what room the item is in.
