If you are using Wantedly People with a Wantedly account-
The card data will be automatically updated and can be used as backup, as Wantedly People organizes cards by saving the data to the account.
It is also possible to view the same card data even if you change mobile devices when you use Wantedly People with a Wantedly account.
If you don't have a Wantedly account-
We recommend our users to make an account so it is possible to have a back up just in case.

NOTE: Card data will be saved on your mobile device before the account is linked. Therefore, if you don't make an account before you change your device, your card data will be lost.
