Hi,
Thanks for your message. With the commercial version of the plugin you can publish the pre-installed payment method called “Offline Credit Card”. This payment method will collect the card details from the guests and will temporarily store them onto your website in a secure way until one week after the check-out date (data gets split before being stored, hence the card number will never be saved as a whole).
This payment solution is not connected to any bank gateway, and so this means that no transactions can actually be made (nor charge nor authorization), and that only a syntactically validation of the provided card data is applied. You need to use a Virtual Terminal with your bank or a physical device to manually punch the card number and process an offline transaction. However, please be aware of the fact that nowadays most transactions will require 3DS authentication data, and so this payment method may not be useful all the times to process offline transactions.
Our suggestion in this case is to rather adopt a real payment processor like the pre-installed PayPal Checkout or any other non-included integration like Stripe to collect payments or authorize transactions (Stripe for example). Also, the payment framework of VikBooking can be extended by creating WordPress native plugins that declare the necessary hooks as described in our technical documentation (payment plugins for WooCommerce or any other WordPress plugin will not work with VikBooking). This is useful in case you would like to use a specific payment processor with your preferred bank.
We hope this is helpful!
