RFID is a challenging bit of Supply Chain technology - depending on your industry. Capital goods manufacturers see a relatively inexpensive solution for accurate asset tracking, while producers of commodity goods see additional costs that are challenging to justify. Many are taking a wait-and-see approach, trusting that the price-per-chip will continue to fall and the supporting technology will develop acceptable standards (to keep hardware maintenance and software stability where it needs to be).
That doesn't keep other industries from coming up with creative things to do with these devices ...
Note that the world should encourage more great ideas, because it all goes towards driving the demand for RFID chips up - which should (hopefully) translate to higher production volumes, better production methods, and lower prices.
