Abstract
Disclosed is a system and method for verifying the authenticity of goods for sale. The system includes an authenticity device on the product which determines a code using a two step authenticity algorithm which inputs time as a variable and outputs the code. The code may be displayed on the authenticity device. The smart device contacts the manufacturer via an application and a wide area network and provides identification information regarding the product. Based on the identification information, the manufacturer finds the copy of the authenticity algorithm stored at the manufacturer, runs the algorithm, and returns the code to the smart device.
