How do I modify my payment method?

You can modify the payment method through the option "Payment methods" found in the side menu of the app. When entering a new credit or debit card, the old one will immediately be deleted.

You can also do it through the Web User Portal: https://webapp.blinkay.app/integraMobile/Home/ 

You can access your account with the same username and password that you use for the app.

Click on "Replace Credit Card" on the left side menu and add the card.

If this process fails, you should speak with the issuing bank of your card to verify that you are not restricted to payments through the RedSys platform
