Consider the ways you use your bank card on an everyday basis, whether handing it over to a cashier, swiping it to make contactless payments, or inserting it into an ATM. How are you holding the card as you do all those things? Vertically, I’m willing to bet, or in portrait orientation, to borrow a term. And yet, the vast majority of credit and debit cards are designed in landscape, sticking to a thoroughly outdated usage model. This is the senseless design inertia that the UK’s Starling Bank is rowing against with its newly unveiled portrait card design, which was spotted by Brand New.

Starling is one of a new wave of mobile-only banks, whose business is primarily conducted through a mobile app. It also issues a debit Mastercard as part of its service (I know, because I’ve got one). Given its diminutive size and forward-thinking ethos, Starling has much more liberty to experiment than traditional banks, hence its choice to flip the orientation of its bank card. Mind you, this is still something of a mongrel design: the rear of the Starling card is still set up in landscape, perhaps to retain compatibility and some level of familiarity.
