The data validation app is especially useful on the checkout page. With the data validation app, you can create rules so that only valid data from the customer is accepted into the various checkout fields. A checkout field that requires the phone number of the customer can be configured to accept only numeric input from the customer. You can also set it to reject special characters and letters. This way, the customer will be informed to only enter a valid phone number, address, or any other details in the checkout field.
