The silver card is a protective card that prevents the NFC TYPE authentication device (Nemo Card, TAG LP, TAG VIDEO, etc.) from being scanned by other devices before opening the package. When the silver card and Nemo Card are together, the Nemo Card cannot be scanned by a smartphone.
To activate the Nemo Card to your account, you must separate the authentication device from the silver card and then scan it using the Nemoz app. When activating the Nemo Album, be careful not to scan the silver card instead of the Nemo Card or scan both cards together!
