Hello,
First of all, congratulations on the excellent work with the Traveller theme — it’s a powerful and flexible solution for travel businesses.
I would like to suggest the addition of a new payment method that would be particularly useful for the Greek market:
support for payments through NBG (National Bank of Greece).
NBG offers its own online payment system, which is widely used by Greek businesses — especially in the tourism sector. Currently, the theme includes various international payment options, but does not provide a way to connect with local Greek banking systems.
It would be highly beneficial if you could consider:
either adding direct integration with NBG’s payment system,
or providing a plugin/hook that allows custom connection to their platform.
You can find more information about the bank and its services here: https://www.nbg.gr/en/individuals
