Do I have to register my credit card to use the app?

Carlo is a payment application which requires you to register your bank card in order to make payments with Carlo and accumulate cashback with our partner merchants.

However, if you have an account that has been topped up with a Top up code, you can use your cashback balance without having to register a bank card. 

I receive an error message while registering my card.

If you encounter an error while registering your card, please verify that:
  1. Your card is a Visa or a Mastercard
  2. Your card is registered in a European country
  3. Your card is authorized to make electronic payments by your bank.
If loading the page takes a very long time while registering your card, please uninstall and reinstall the app. 
If the problem persists, do not hesitate to contact us at
