London FinTech Curve has expanded its wearables offering by partnering with Garmin, Fitbit and Sony’s Wena pay.

Curve, which allows customers to integrate all their banking cards into one, is now enabling users of some of the world’s most popular wearables to pay with any of their cards using Curve.

Integration with digital wallets, starting with Google Pay and Samsung Pay in November, allowed Curve customers to pay with their mobile phones. This has now been extended to smart watches.

Curve customers who upload a card to their wearable device can now pay with any bank, even if it was previously incompatible.

Customers of all three of the wearables’ businesses also benefit from Curve features including fee-free cards when spending abroad, one per cent instant Curve Cash, Curve-fronted debit payments when spending on credit cards, spending insights and going ‘back in time’ to transfer money between accounts up to two weeks after a purchase has been made on Curve cards.

“Wearables are fast becoming one of the most convenient ways to pay for things on the go,” said Diego Rivas, Curve’s head of product OS.

“Bringing Curve’s unique all-your-cards-in-one benefits to three of the biggest players in the wearables space, and enabling their customers to be able to pay with any bank using the Curve platform truly cements Curve as the ultimate way to manage all your finances in one place.”

In September Curve became the fastest start-up to raise £4 million in crowdfunding. After initially smashing its £1m target in under five minutes, the round was eventually closed around £6m after being massively oversubscribed.

In July Curve closed its series B funding round, valuing the business at a quarter of a billion dollars. The company has also announced plans for European and US expansion in 2020.
