Especially, provided that this actually a good old tab interface. Not that there had been a time when we knew how to make tabs unambiguous that anyone could still remember, but… Ok, on closer inspection, is this rather a horizontally laid out select (or radio group)? Does the content below change with options? Is there anything, so we could tell, whether it's tabs or a select and what the consequences are of choosing either option? Is the vertical white space a functional divider/separator or just flat UI design? I guess, the transaction business is just a leap of faith…
