The data backup/synchronization in the cloud keeps all data up to date in seconds. Furthermore, the devices communicate with each other constantly within a store, so that you have access to all tables, orders and processes from every other device (floating guest check, cross-regional bookings possible).
Even if you lose your iPod or iPad, your data is safe. It is stored in encrypted form and can only be accessed with your login data. Furthermore, we can immediately deactivate individual devices if necessary.
