The data necessary for authentication is transferred with the application program from an SD card to another SD card. Authentication fails if you try to use the SD card after you move the application program from one card to another card.
Do not use the SD card if it has been used before for other purposes. Normal operation is not guaranteed when such an SD card is used.
An SD card, which becomes empty after moving the data in it to another card, cannot be reused.
After moving the data in an SD card to another card so that the source card becomes empty, keep the empty card in place by, for example, affixing it near the SD card slot with adhesive tape. This is done for the following reasons:
The SD card can be the only proof that the user is licensed to use the application program.
You may need to check the SD card and its data to solve a problem in the future.
