Thank you very much for your interest in the plugin.
As for now the payment processing with a spanish bank ( BBVA ) with TPV that you have mentioned is not available to use with the WP Travel plugin. We do have other the payment gateways that works with the dollar, Pound and some other European currencies but not the one that you have mentioned.
However our team is always very open to the suggestions and features obtained from our customer so regarding this payment processing as well, we will definitely work on this In future.
But if you want then you can hire a freelancer or our professional developer to build a separate payment addon for you.
Hope this clears the confusion.
If you have any issues further then kindly let us know.
