A method of identifying or authenticating a product by providing an analog identification indicium including a randomized pattern of identification features on a first part of the product wherein one or more attributes of the randomized pattern of identification features correspond to an item identifier. A digital identification record is provided on a second part of the product including an encoded digital version of the item identifier, the first and second parts being separable when the product is used. The randomized pattern of identification features of the analog identification indicium is read and decoded to generate an item identifier and the digital identification record is read and decoded to generate an item identifier. If a special light source is necessary to read the randomized pattern of identification feature, a flag is present in the analog identification indicium or the digital identification record that indicates one or more types of light sources that can be used to read the identification feature. The appropriate light source is activated to read the identification feature and if the appropriate light source is not available the user is alerted to this fact. The product is deemed authentic if the item identifier from the analog identification indicium substantially matches the item identifier from the digital identification record.
