My transaction was declined, what could it be?

😬 Payment Declined? Don’t Panic!

In our experience, it’s usually down to that pesky but important SCA (Strong Customer Authentication) limit doing its job—keeping your money safe and sound. đŸ›Ąïž

Here’s what’s likely happening:

  • Once your contactless transactions add up to £300, your next tap might get declined.
  • It’s not a bug—it’s the system checking that you’re still the proud owner of your Twinn wearable.
  • To reset things, just grab your physical Bank card and make a Chip & PIN payment.
  • That’ll satisfy the system, reset your limits, and send you merrily on your way. 🎉

🌍 Travelling? SCA limits vary by country. You can find the full list right here.

đŸ€” Still Not SCA?

If you’re sure it’s not the SCA limit, we recommend:

  • Checking your online banking
  • Contacting your card issuer to see what’s up

They’ll be able to give you the lowdown on what happened.
