When the IIN does not match any of the products that are configured on your account an invalid response is returned. This means that we will not be able to process this card, most likely due to the fact that your account is not set up for certain specific card products that the consumer is trying to make the payment with.
I was trying to get the new expansion here, using a visa card that I use for all my online purchases. It is valid and have been recently used elsewhere. This is still and issue and have been for some time.
Consumer rights
Consumer rights are enhanced, including:
reduced liability for non-authorised payments from €150 to €50;
an unconditional refund right for direct debits in euro for a period of 8 weeks;
the removal of surcharges for the use of consumer credit or debit cards.
The European Commission produced a user-friendly electronic leaflet listing consumers’ rights under the directive and related EU law.
As an informational update, I want to share this list of IINs. Most of these are not accepted at the ESO Store since May 2024. These are just some of the IINs for Barclays Bank in the UK. You can use this site to look up the IINs for your own bank and test them on the ESO store.

As well as checking the IINs from both of my cards, I ran through a bunch of other IINs from my bank and was able to confirm what Worldline Global have told me.
