Jacek Uryniuk, for Cashless:
[…] this Tuesday will be the day Apple Pay becomes available for the customers of Alior, BGŻ BNP Paribas, BZ WBK, Getin, mBank, Nest Bank, Pekao and Raiffeisen Polbank. More banks will follow in the fall, probably in September. They will supposedly include Poland’s biggest retail bank, PKO BP.
The list of banks is more or less what I’ve heard myself, from another source, but the date should be solid, if there are no technical difficulties.
