BLIK has started blocking transactions to illegal iGaming operators in Poland as of September 1

Poland’s most popular payment system, BLIK, has begun blocking transactions to illegal iGaming operators from September 1. For PSPs and merchants in high-risk, the point is straightforward: if a payment rail is actively filtering out unlicensed gambling flows, routing and acceptance logic need to be adjusted accordingly.

1. BLIK is now blocking transactions headed to illegal iGaming operators in Poland, with the new measure taking effect on September 1.
2. The original report describes BLIK as Poland’s most popular payment system, which makes this a relevant change for anyone handling local payment acceptance in gambling and adjacent high-risk verticals.
3. For operators without a local licence, this means one more mainstream payment method is no longer available for deposits. For PSPs and acquirers, it is another reminder that domestic payment rails can and do enforce vertical-based restrictions at the transaction level.
