What is RFID technology?
Radio frequency identification (RFID) is a technology that has been used to identify and track livestock animals. You’ll find RFID in action on dairy farms for example, where cows often have high-tech collars that help the farmer track how much the cow is eating and how much milk she is producing. Researchers suggest that this “tagging technology” could be expanded to crops, so that an individual crop could be traced more efficiently from the farm to the table, using a simple computer chip. RFID has already made it into the hay-bailing market where farmers use the technology to track large bales of hay and keep track of important characteristics such as weight and moisture level.
