Re: Electronic serial numbers
"I have designed these things into products for very good reasons in the past as there are clear benefits - automatic scanning of device ID to eliminate human error at manufacture or repair return comes to mind, a use case I have had."
At the warehousing and sales level a serialized RFID that has the serial number of the product can be used for inventory and routing. It would be very expensive to ship a container full of products to a region where that product won't work. Or even just a pallet that gets mis-directed.
