About Barclaycard:-
In 1966, Barclays saw a need to make it easier for people to do business – for customers to buy and shopkeepers to sell. In response, they created a new company called Barclaycard. We launched the UK's first credit card, and in the years that followed Barclaycard grew rapidly: through new technologies like mobile and contactless, and into new markets around the globe. Today, Barclaycard is one of the leading payment providers in the world.
From small beginnings in Northampton, we've built a team of 11,000 employees serving 36 million customers worldwide. Barclaycard is now the leading credit card issuer in the UK, Germany, Spain, Italy, Portugal and the Nordics – and we're just getting started. We're pursuing our goal to make Barclaycard the ‘Go-To' choice for consumer payments.
You'll find Barclaycard on both sides of a transaction. We provide shoppers with credit cards, loans, and innovative new forms of payment, and we provide sellers with the technology to accept and process payments. In 2013, we processed over £235bn in transactions.
From the beginning, the Barclaycard story has been one of innovation – from the UK's first credit card and cash machine to the first mobile and contactless technology. We were the first company to give women a credit card in their own name, and the first to create a card that's managed by members through an online community – Barclaycard Ring.
It all started with a card, but these days we're looking past plastic. We're exploring new ways to pay, including wearable technologies like bPay band and products like bFlex, which lets you finance a purchase at the point of sale. Because just like we did in 1966, we're here to make things easier for everyone.
