AFAIK all of the Capital One cards have no additional bank markup (above the brand-imposed fees). The VISA brand is apparently imposing 1%, although this was not charged to 2 GBP transactions for me last week. Because this VISA brand markup is currently in effect, I expect Capital One to pass it on some time soon. The MasterCard brand is scheduled to remain at 0% until this autumn.
