Electronically readable system and device with changing codes
Abstract:
An electronically readable device and system is incorporated within and/or attached to an object to validate and/or authenticate the object. Upon activation of the device one or more codes encoded within the device are revealed and are able to be scanned by an electronic device. The electronically readable code changes, such that for each period of time the code is different than a previous period and only the database knows in advance what the code should be for a given period. The scanned code is uploaded to the database where it is compared to a stored code to verify that the object is authentic.
