What if the pallets formed a mesh network? They would only need to have low-powered antennas (< 100m range) to network effectively with one another, and some kind of reader that talked to one could know all the other pallets that that one had "seen" and at what time. It would take a bit of work, and would be most practical for large pallet storage areas, but it could hugely cut costs, especially for wireless internet.
