摘要:
A combination RFID tag intended to be associated with a host product, for example by being secured to the outside of a package containing a perishable product, e.g. foodstuffs or vaccines, which RFID tag is provided with a visually readable environmental condition exposure indicator. The visual indicator can sense the exposure of the RFID tag to an environmental condition e.g. temperature, experienced by the host product providing a visual indication, e.g. a color change, readable externally of the RFID tag of the sensed environmental condition. The visual indicator can be chemically active, for example an acetylenic agent, and may be responsive to cumulative temperature excursions over time. The novel RFID tag 11 and tag inspection methods of the invention permit an efficacious harnessing of information about the condition exposure history of a specific inventory item including product identification and related data. The information from multiple items can be compiled into a database that may be audited or statistically analyzed to reveal useful information regarding the handling of the items.
摘要:
In part, the invention relates to computing systems and methods for electronically indicating the acceptability of a product. An image capture and communication device may analyze a product label that includes one or more monitors, authentication elements, and identification elements. The image capture and communication device may determine the type and features of the monitors, authentication elements, and identification elements. The image capture and communication device may transmit data based on the type and features to a host server, which may transmit data associated with the host product to the image capture and communication device in, inter alia, the form of an acceptability report.
