PKO Finat, Kropka lottery

100,000

receipts a month verified through AIS

PKO Finat, Kropka lottery

In the Kropka lottery, Fizen confirms, with the participant's consent, that an added receipt matches a real transaction from their account.

It was one of the most pleasant and trouble-free integrations of my career in digital banking. Together we proved that PSD2 and open banking do not have to come with a pile of technical problems.
