Curve is a Mastercard® debit card. You can use Curve like any other debit card, anywhere Mastercard® is accepted.
Your Curve card doesn't hold funds like your traditional bank cards, simply add your cards to the Curve app and select the card you'd like to spend with through Curve (you can read more on this here).
If you encounter any issues when spending with your Curve card, raise a ticket in-app or email support@curve.com. We’re happy to help!
