If you have already added your Openbank cards to Samsung Pay you must update them. To do this, select the cards where a blue icon appears above them. Click "Update Card" and register your card again with Samsung Pay. You can do this by scanning your card, entering the details manually or bringing your card close to your mobile with NFC. After accepting the terms and conditions, you'll be asked for a confirmation by SMS to complete the process.
