Abstract
A method for tracking products as they move through a supply chain is disclosed. The method involves using an identification tag reader to scan a machine-readable identification tag that is attached to a first product. The machine-readable identification tag includes an encoded version of a product identifier that uniquely identifies the first product. The identification tag reader decodes the encoded version of the product identifier and obtains the product identifier. A product database is then accessed to determine whether a next action that may be taken with respect to the first product is allowable. The next action is not allowable unless a current value of a state associated with the product identifier in the product database is equal to one of a set of allowed values.
