Yes - it’s blik contactless which was developed with Mastercard - it’s sometimes visible on receipts. but perhaps wide adoption might motivate Blik to develop their own system without USians.

I use always for online payments - super convenient. Recently started using it for self-checkouts at grocery shops - unfortunately much less convenient than card: i need to take out phone, confirm transaction, write my pin compared to pay with apple wallet with faceid its much slower. There is also blik contactless for android phones but it’s developed with mastercard.

Thank you for this insight, very informative! Will definitely check it out.
