Full Credit Card data should never go through your server.
Do not send the credit card data to Omise from your servers directly.
The methods described on this page should only be used either with fake data in

a terminal, etc.), or if you are PCI-DSS compliant.
Sending card data from server requires a valid PCI-DSS certification.
