A method for verifying authenticity of an object includes the steps of: enabling a code-generating device to generate and show a symbol based on at least two of a unique identification code of the code-generating device, and first and second authentication codes generated by the code-generating device based on a varying secret key; and enabling an electronic device to forward an image of the symbol to an authenticating device for verification. A system, which includes the code-generating device, the electronic device, and the authenticating device, and which performs the method is also disclosed.
