1. Tap on "Settings" at the lower right, and the Settings screen will come up.
2. Select "Sync now"
When you tap this, you will be prompted with "Synchronization will start. Would you like to proceed?", so please press "OK".
Synchronization may take some time.
*Problems such as card numbers being different than the PC version or error messages coming up will most often be solved by synchronizing. However, if this does not solve the problem, please delete the Smartphone app and try reinstalling it.
