I wonder about putting some sort of camera-readable code or even a wireless signaling device (passive/reactive?) on the packaging, even as stickers, a modern equivalent of barcodes for their readers. Amazon would have to add the stickers for now, but it could revolutionize retail. IIRC I read that a bookstore chain revolutionized their retail industry by putting barcode stickers on all their books, allowing computerized inventory, and now publishers print them by default.
