You can now create an account in the WhatsMine app or simply sign-up using your Google Account. This will allow you to sync all your loyalty cards across multiple devices. If you are changing devices, but already have an account, you can simply log in and you'll be able to view all your loyalty cards in once place. 

 Please go to the 'Accounts' section in the app to 'Create an Account' or 'Log in' to secure and backup your date.
