If you subscribe to the cloud service, you can enable credit card collateral on your checkouts. The most common practice is to operate on a late fee principle. Here you can set a time period where the checkout is free, and the system will charge a late fee at set intervals for overdue checkouts.
The fees collected are held as a balance in your account and can be paid out or used to replace old chargers.
If you wish to change or remove credit card collateral from your checkouts, please contact our support team at email@example.com
