It's hard for me to imagine that it makes economic sense to use rfid for relatively inexpensive, non serialized food products, as the example shows. That being said, it is much more useful for preventing theft for clothing and higher dollar items. Any idea what the cost is "per tag?"
It could be.
The printed electronics platform supports memory and logic and RF circuits and a sensor technology.
In this food packaging application I am not sure the RF communications channel has been specificed but RFID might work.
