In previous applications we’ve seen, EMS Antennas are often sunk into the floor of production or assembly facilities. Tags on product, or forklifts pass over these antennas, and relay information to the operating system. P&G reversed this tag/Antenna relationship, sinking RFID tags into the cement at strategic locations between the conveyers and dock doors. Tags are written to with information regarding their location, and serve as geographical markers. Antennas, mounted to the underside of the forklifts, pass over the tags in the floor as the Forklifts drive up to the loading dock form the conveyer. When a pallet comes off of the production line, fixed barcode readers scan barcodes on the package, then relay to the PLC information about what product is on the pallet. Forklifts with antennas mounted to their undersides move the pallets from the conveyer to the dock doors. In this process they pass over the tags in the floor, which have been written to with a serial number to indicate their location. These tags serve as markers, so that when a forklift loads up a truck, operators have record of what product has been loaded and know exactly where it has been.
