State University, are using the RFID tags to tackle a tricky problem: How to improve an already cash-strapped industry with technology. Researcher Anthony Laws admits the trackers will cost farmers cash up front. The entire system would cost about $3,000 to implement, and he knows it’s cash not all farmers are willing to spend.
