UK here, also got the email.

I’m also interested in this. The biggest issue is that a lot of the proposed services in this thread are debit cards not credit cards. They don’t come with the same buyer protections from fraud and bad merchant behavior. Some do offer protection but the terms of it are a bit different.

I’m looking for a credit card with unlimited active cards that I can revoke on demand, Starling for example limits you to 5 active (Starling are great BTW). To be truly useful to me I’d want each merchant to get their own card.

I’m warning anyone that will listen against Curve. It worked great until the two times I needed support (one where I got double charged for something, and another was fraud related). You can’t contact their support team. There’s no phone support, even for ongoing fraud. If you phone them they redirect you to a form to fill in. I never got a response from them.

Worth giving SimpleLogin.io a look. It has customizable display options for this. (not affiliated, just enjoy using it)
