99% of Poland Bank issues Debit cards, IBAN numbers, SWIFT codes have all been black listed by most of the western banking/financial sector.
You can not use PLN cards to verify paypal, ebay, amazon, or any other payment gateway. If you link a PLN IBAN to paypal you will get limited quickly.
These are rubbish cards. They are all black listed. Find some better.
These are not blacklisted anywhere. What proof do you have?
They work with paypal and ebay at least. I haven't tried with amazon.
Where are the better alternatives?
