We're big fans of efficiency. Case in point: our phone tells the time, takes superb photos, and can even bake a jacket potato (one of those is a lie).
Which is why we love this belt buckle card holder. Not only will it mean you won't have to carry around a bulky wallet, there'll be no more wondering if you left it at home, or worse if it's been nabbed by a pesky pickpocket.
Dubbed the smart belt buckle, the accessory allows you to keep up to three bank cards as well as business cards and ID. It's available in brushed metal, gunmetal and titanium, and you can even get it personalised.
The best news? You can buy it right here for £26 ($39.95).
