"WIRELESS: RFID Tags + MEMS Sensors Track Food for Safety"

Radio frequency identification (RFID) tags can now track food shipments and even keep track of the conditions under which it was stored, giving the trillion-dollar food industry a method of quickly recalling items and making more intelligent shelf-life predictions. Look for smart RFID tags with embedded MEMS sensors within five years. R.C.J.


When you see a "today's special" sticker on meat at the grocer, its hard not to imagine that the sale was prompted by a clerk leaving the meat out of the refrigerator too long. With radio-frequency identification (RFID) tags in the package tracking temperature, your fears could be allayed, according to the Institute of Food Technologists (IFT) which features RFID tag use in this month's issue of their flagship publication, the Journal of Food Science. In the October issue of the JFS, researchers detail the range of future uses for RFID tags in the trillion-dollar food industry which employs about 17 million people in the United States alone.
