The error is most likely due to problems with Secure Customer Authentication (SCA).
If you have an issue with the following:
Referral A: This is a response that you can receive when a transaction is sent for authorisation. When an authorisation receives a Referral A, the card has been marked as lost, stolen or cancelled. Payment will not be taken.
Referral B: This is a response that you can receive when a transaction is sent for authorisation. When an authorisation receives a Referral B, the issuing bank of the card holder will not allow the transaction to go through automatically and is requesting that you call their authorisation centre to process the payment.
When making payments by card you should be aware that there is a daily limit on card transactions imposed by your bank. You can get around this by making a series of transactions smaller than €1,500. Alternatively, you should contact your bank and ask them to authorise a larger payment amount.
Please ensure that you advise your bank of your impending transaction so that they do not place a security block on your card. This is especially important for transfers for international students.
