Bringing Amex Back to Curve

You are probably aware that American Express has decided to block our customers from adding their Amex cards to Curve and making top-ups to their e-wallets. Amex has given no good or fair reason for their decision and we believe it to be entirely disproportionate and discriminatory to Curve and our joint customers.

Although Amex cardmembers represent a small percentage of our customers, we believe Amex decision to be wrong. We believe consumers should be able to decide how they wish to access their money, and that progress should not be stifled by the whims of giants. So we decided to stand for what we believe in: that real innovation can prevail. Curve is an original and groundbreaking product that gives you, the consumer, greater control over your money and we are convinced that this is worth fighting for.

Before I ask for your support of Curve in its fight for innovation and a level-playing field, let me share how this situation with Amex has come about.

Amex First Comes to Curve

In 2016, when we launched Curve in Beta, we accepted Amex cards as one of our funding options, alongside Visa and Mastercard. We soon found out that Amex did not like this operating model, and were promptly told to remove Amex support from Curve. Back then we were a small startup with limited resources and, though disappointed, we were forced to acquiesce and continue to grow our business without them. This was a time before the game-changing PSD2 came into force and regulations did not forbid Amex from doing so.

Although Amex’s market share of total card payments is less than 10% in the UK, it is a leader in the rewards market. Curve cardholders who also have an Amex card represent a small segment of our customers, but for them, Curve can’t be ‘All Your Cards in One’, and they still need to carry two cards in their wallets. Moreover, the bigger problem these users have is that Amex acceptance in the UK and Europe is low, so they can’t use their Amex as much as they’d like to. All of the above explains why many of these customers asked Curve to bring back support for the Amex network.

PSD2 Introduces a Level-Playing Field

In January 2018, the EU’s PSD2 came into law in the UK under PSR 2017, and turned the payments industry on its head. It opened up the payments market to competition and innovation. In particular, it ensured that companies could access all payment networks (including Amex) on a level-playing field along with every other fee-paying and legitimate payment service provider.

As a consequence of this radical change, Curve applied for a new merchant account with Amex and signed a Merchant Services Agreement on the 23rd of March 2018. The Amex team knew the history with Curve but were very happy to start working with us again. In fact the leadership team at Amex Europe were supportive and engaging and we jointly came up with the traditional top-up (prepaid) model approach that Curve launched this week.

In particular, I personally spoke with Amex’s Head of Merchant Services in Europe, who gave his support and endorsement to our plan, understanding that the top-up model they requested differed markedly from how we operate with other card networks. He was happy to have this distinction.

Aside from having a standard merchant agreement with Amex - allowing Curve to accept Amex cards like any other merchant - Curve never had a formal ‘partnership’ with Amex, nor have we sought such an arrangement.

On the 19th of November, we re-launched Amex to a small group of Curve customers, as we do with any product (‘Closed Beta’). It is important to note that the Closed Beta wasn’t part of an agreed roll-out with Amex, nor was there ever a discussion on needing permission from Amex to roll it out to our customer base. Based on the agreement with Amex from March 2018 and the information we had, Curve could have rolled out Amex support to all its customer base in November - when the MVP was ready. The Closed Beta results were remarkable. Around 500 customers topped-up over £1 million in less than a month and their activity on the Curve platform increased by 25%.

Daily communication with Amex employees was nothing but positive and encouraging throughout our Beta launch. They did express a desire to be involved in our launch communication plans and requested a meeting to align communications prior to our wider launch. The meeting was postponed to early January and then moved again at their request to Monday 21st of January. We continued to push back our main Amex launch accordingly, in order to respect their wishes.

The Meeting on Monday 21st of January

The official reason given for this meeting was to discuss Curve’s PR strategy for the main Amex (‘Open Beta’) launch, knowing that we planned to launch shortly. Instead, to our surprise, the Amex team stated that they were unhappy with the Beta, acting as if it were a joint operation. Amex raised concerns over customer experience without giving more details. This flew in the face of the data we had collected and our direct customer feedback.

To be absolutely clear - this was the first time Amex ever mentioned any uneasiness with the integration, and it was never the case that we required Amex approval for the launch. Curve received written approval to launch Amex support in Curve the moment Amex signed the Merchant Service Agreement.

We reminded Amex that strictly speaking we did not have a partnership but rather a Merchant Service Agreement, and if they wished to terminate it, the contract required Amex to give Curve 180 days’ notice. Moreover, we shared our legal opinion that by doing so they might be in breach of payment regulations and could demonstrate clear anti-competitive behaviour if they prevented Curve from accessing the Amex network - as they allow exactly the same functionality to other merchants, such as Paypal, Upay and Yoyo Wallet.

The meeting finished without Amex giving us any formal notice and we agreed to continue the conversation at their offices at a later date.

Amex Launch vol 2

Our launch was planned for Monday 28th January. With this in mind, we decided to regroup to reflect: what would be best for our customers? Should we delay yet once again to an unspecified date, or launch? We decided to move forward with the launch for several reasons. Our Merchant Services Agreement was perfectly valid and our top-up mechanism was known and agreed-upon with Amex. Moreover, our legal advice told us we were protected by regulations, and Amex were unable to prevent Curve from accessing its network.

The first day of the Amex launch was remarkable. Curve customers, especially those who were already Amex cardholders, gave us positive feedback on social media, and spent more than £450,000 on Curve via Amex in one day.

Then, the bombshell. On Tuesday 29th January at 4.46pm UK time, Amex notified us that they were terminating their Merchant Services Agreement with Curve with immediate effect. With that move, and based on legal advice we received, Amex breached their contract with Curve, failed to give appropriate notice, breached PSR regulations, and demonstrated clear anti-competitive and anti-innovation behaviour. Most importantly, Amex seemed to show a total disregard for its own customers’ interests.

Next Steps and What You Can Do to Support Us

We know that without your help we wouldn’t have achieved the heights we have reached to date. With your interests in mind, and our mission to deliver a truly innovative product, we intend to challenge Amex’s decision. We believe financial freedom is the future and we are prepared to fight for yours. This is not really about Curve or Amex; this is about you. It is about putting the customer at the centre and fostering a level-playing field in the financial space.

To be clear, we are not asking you to slander Amex - we are still trying to understand the reasons behind their actions and hope to reach a commercial resolution. We have already sent a letter to them to reconsider their decision and have given them reasonable time to comply. Failure to do so will mean that we will be forced to exercise our rights in the courts and to submit complaints to the relevant regulators in the UK and Europe.

You can support our cause by tweeting to the PSR and FCA , and letting Amex know your thoughts. Explain the benefits you see in supporting Amex in Curve, how it increases competition and choice, and request to review their decision.

We’re sorry for any inconvenience caused to Amex card members, and we hope to resume Amex support in Curve soon. We will update you as soon as we have any further information.




Here’s hoping the merchant agreement can be restored! Amex shouldn’t have pulled the rug out from underneath Curve. Thanks for the update.

Thanks for the update - it does seem an unfair decision.

Thanks for the update and hope AMEX brings on Curve back soon.

Supported - you only need to look at Paypal, YoYo and any other e-wallet to see that (on the face of it) Amex is not treating Curve fairly, and is also hurting it’s own customers that want to use Curve. If anything, Amex are directly limiting their own revenue by refusing to allow Curve use and the wider acceptance it brings.


Exactly. Well said that man!

I will continue to support Curve, I believe the product you have is like no other. I wish Amex was still on the platform of course.

However I do feel given Amex told you they were unhappy with the beta you should not have launched to the public, things should have been resolved first. While this wasn’t a great move by Curve, it’s clear to see Amex are treating you unfairly and I hope things can be resolved soon! :slight_smile:

Hi. Thanks for the update and curve do get my full support! Have sent tweets and feedback to both the links.

Not to bring negativity, but i am interested to know what will happen to the subscription model in the mean time? Will everything be rolled back??? Or is the trial period going to continue.

Awaiting confirmation on this. Will write an update ASAP. Update: Metal Subscriptions & Cancellation


Thank you for your side of the story.
What I’m missing is the logic behind only accepting UK-issued Amex cards. Correct me if I’m wrong, but surely there are no other Merchants that would be allowed to limit Amex use like that?

Basically this sounds to me like Amex pulled a **** move, and Curve were naive in expecting them not to. Launching to the public (and taking subscription fees) when they’d been told Amex weren’t happy seems a little irresponsible, regardless of whether Amex’s position is unreasonable.

Best of luck to the team. I’ll be interested to see what happens with the subscription model now, but if we’ve learnt anything this week, it’s that product changes shouldn’t be rushed, so I’m happy to give Curve a bit of time to work out how best to proceed.


My support is also with Curve, however I feel that I was used in a way to put pressure on amex.

It would be good to know something in advance, since I didn’t read anywhere that those meetings were confidential!

In any case, looking forward to a statement about the future of subscriptions and us who updated.

That is odd. I’ve been using my card for TFL travel the last 2 days and have no transactions recorded on the app… everywhere else I have tried to use it has been rejected.

You have my support guys!

One solution can be to treat the Amex cards the same way as Visa/MC like before, but with the fee of 0,65%. That way Amex doesn’t feel it as competition but the other way around, gaining great new spend to the Amex network in new EU countries and merchants. Curve on the other hand doesn’t release the product in Amex home market USA.

Curve members will of course always prefer to use Amex where accepted instead of paying the fee. The perfect combination for many users like Myself!
First £1000 included in the new subscription Black.

Hi there, I just wanted to give you a heads-up, as I just had a phone call from AMEX “fraud protection” service (I did verify their number too), as they specifically wanted to check if the top-up I was doing to Curve was a legitimate purchase, and if I was happy with the purchase etc. Just thought I would give the head-up, in-case others got this too

That’s probably a standard procedure if the transaction differs from your established spending pattern.

FWIW, my Oyster Auto-top-up (via Curve, with Amex wallet) went through today.

I know that it may take a few days for TFL to properly calculate your actual charge for your trips. Have you registered your Curve card with TFL? If so you can check on your TFL account and see if the charges appear there at all.

Your card being rejected everywhere else may or may not be related to your missing TFL charges.

Hi Mattias,

Thanks for your comment. To be clear: the request to do top-up came from Amex. We wanted to operate like we do with Mastercard and Visa.

We took 6 months to build the top-up functionality in the front-end and back-end to accommodate this.

I find that an odd request…

Doing it this way means Amex have less visibility on the transactions than banks that issue Visa/MasterCards… CRV**Something would mean more to Amex than a simple wallet upload with no knowledge of what people then do with the funds…

With that additional visibility Amex could then alleviate their concerns by making it easier to spot people doing cash recycling etc.
