Abstract

A method of introducing a verification check to a product is provided. The method comprises generating an alphanumeric code associated with the product, using one or more digits in the code to calculate a resultant value and modifying at least one digit in the code based on the resultant value. The resultant value determines the form of modification based on a predetermined selection of possible modifications.

Description

technical field [0001] The present invention relates to a method of printing a verification code of a product, a method of verifying the authenticity of a product and a verification code. Background technique [0002] Counterfeit goods are a big problem in many industries, especially in developing countries. They can erode consumer confidence or, in extreme cases, cause real harm and cause losses to manufacturers and distributors. Over the years, various methods have been used to allow authenticity of items to be verified, including holographic tags, RFID tags, and overt and covert codes. While these methods may provide a means of detecting counterfeit items, they also involve additional cost and / or complexity to the production process. [0003] A variety of techniques have recently been proposed that involve the manipulation of existing codes and / or information on products for tracking purposes. For example, WO 2012 / 109294 A1 discloses a method of printing a product code...
