Abstract
According to an embodiment, a printing apparatus mounts an ink ribbon provided with a wireless tag storing a digital certificate that is generated using an encryption algorithm on the basis of a private key and a unique identifier (ID) of the wireless tag. The printing apparatus communicates with the wireless tag, and reads the unique ID of the wireless tag and also reads the digital certificate stored in the wireless tag. Further, the printing apparatus verifies the digital certificate on the basis of a public key and the unique ID read from the wireless tag to determine whether or not the ink ribbon is a genuine product.
