Abstract

A system and method for improving supply chain visibility is provided. According to a preferred embodiment, an electronic manifest may be downloaded and linked or attached to an existing purchase order. This electronic manifest is preferably designed to accepted data from RFID devices and other sensors. Further, the electronic manifest is preferably configured to be easily accessed the carriers or others in the chain of custody. According to a further aspect of the present invention, sensor-enabled RFID tags may be employed to track a product through the supply chain, capture temperature data, and to calculate shelf life.

Claims

1. A system for monitoring the proper transport of selected items, the system comprising:

a plurality of sensor enable RFID tags, wherein each sensor enable RFID tag is configured to send and receive RFID data and identification information related to a monitored item, further wherein each sensor enabled RFID tag is comprised of;

a first sensing element, wherein the first sensing element is configured to produce environmental data;

a storage element, wherein the storage element is configured to store product storage information and environmental data; and

a processing element, wherein the processing element is configured to analyze environmental data and stored product information to determine whether a monitored item is currently being maintained within desired environment conditions;

a coordinating RFID element, wherein the coordinating RFID element is configured to be attached to and transported with a group of monitored items;

further wherein the coordinating RFID element is further configured to communicate with a plurality of sensor enable RFID tags attached to one or more monitored items;

further wherein the coordinating RFID element is configured to receive a first set of environmental data from one or more sensor enabled RFID tags;

further wherein the coordinating RFID element is configured to receive a second set of environment data from a fixed monitoring element, wherein the fixed monitoring element is not attached to the monitored items and is configured to provide environmental data for a fixed monitored area;

wherein the coordinating RFID element is configured to trigger an alarm in response to an alarm event, wherein the alarm event is determined by the coordinating RFID element, further wherein the alarm event is determined based on a comparison of one or more stored acceptable temperature ranges for the monitored items and historic temperature data recorded by the fixed monitoring element for the fixed monitored area;

further wherein the coordinating RFID element is configured to store the first set of environment data and the second set of environmental data.
