I was FINALLY able to verify my age

If you are a member of the Curve App, or Curve Pay
especially if you have a Samsung phone, as Curve/Curve App is in the process of ending their partnership with them

Switch over to Curve Pay, if you're on the curve app, and it will change to the Curve Pay credit card, with no every steps

then like me use it verify your age

Although, I did have an issue at the beginning, but once I contacted steam support and sent the information they requested, they updated my account, and I was able to complete the verification process using the Curve Pay Credit Card

Looking further into the card it does seem to have a little credit, I think around £250, I’m not too sure. How it works is that you connect your card from your bank account to the curve pay app and any payments you make on the curve pay credit card is taken directly from your bank account, not from the £250, as a result also offers the Section 75 and chargeback protection, which come standard with credit cards.

At least that’s my understanding
That is as long as you don’t use their Flex service, which I believe is like a mini-loan/Credit, similar to PayPal 3-pay system, you won’t owe them anything.

What's great about Curve, is that they did not ask if I'm employed or have a regular income, which always stopped me from being able to apply for a standard Credit Card.
