On second thought, a 'library' type security system might be 
just what you need.

Each box gets its own unique strip -- no active parts, no
batteries, just a computer to keep track of the box and its strip
signature.  Ping the whole pallet and listen for the unique
signature of the wanted box.  Build some df into the listener and
you could ping a whole quadrant or shelf area of the warehouse.
So over all you need the strips, a database manager for the
signatures, and a smart listener that will say yes/no for one
particular signature.
