The 2017 WIRED Money event presented the next generation of fintech startups set to revolutionize the world of finance to its attendees. At the time, EY’s head of fintech, Imran Gulamhuseinwala commented on the winner, mobile wallet platform CURVE:

I’ve seen quite a lot of innovative products and I’ve not seen anything quite like that before.

What is Curve?

Curve is a London-based fintech startup that owns and operates the digital smart multi-card named after the parent company. This niche product is really distinct from both traditional and innovative banking experiences provided in Western societies.

A multi-card is a smart device in the form of a regular MSR bank card (or very similar to it) that is directly connected to a relevant mobile app able to store and transmit financial and personal data. The cards are typically equipped with a small touchscreen display where the user can choose which of the available cards to use for a transaction.

Curve’s “over-the-top banking platform” turns your mobile phone into a centralized financial control center. Instead of building a new current account — as is the case with the challenger banks such as Monzo, Starling, and Revolut – the platform lets you connect all of your other debit and credit cards to an all-in-one simple and secure Curve Mastercard. Therefore, all of your financial services are united under a single digital umbrella that allows you to spend, see, and save money all along. By the way, around 15% of Curve’s users have added a challenger bank card to their Curve account.

Last year, the startup raised $55 million in a new funding round that valued Curve at $250 million. The money will be used by the company to continue adding more features to its platform and for further international expansion.

How to use the Curve card

Currently, the service is facing serious technical problems. On 26 June, the Financial Conduct Authority suspended its permission for Wirecard Card Solutions Limited (the company who currently issues the Curve Cards and processes transactions) to operate, without prior notice or warning. This has not only affected Curve but also infringed the activities of many other companies relying on Wirecard in the financial sector. Hence, the company began a transition away from Wirecard and is moving down the path to complete this migration. Today, Curve is almost back in business, having completed “Phase 1” of the recovery plan. Users will need to update their Curve App and re-verify some of their cards.
