Abstract
In a method and system for providing anti-counterfeit and product safety to a manufactured item, two substantially unique verification codes, one readable and the other hidden, are associated and supplied with the manufactured item. The verification codes are initialized to a first state at a validation service. Either or both codes may be submitted to a validation service for validation for any number of occasions, with the validation service responding with a message appropriate to the current state of the code. When the hidden verification code is exposed and submitted to the validation service for validation, a first successful validation is used as an event that triggers a state transition of both the readable and the hidden verification codes from the first state to a second state.
