KNF SPI Registration & Polish Payment Services Act
Poland implemented PSD2 through the Act on Payment Services (Ustawa o usługach płatniczych), which introduced the Mała Instytucja Płatnicza (MIP — Small Payment Institution) category. The KNF (Polish Financial Supervision Authority) supervises registered MIPs and issues and maintains the register of licensed payment service providers.
The Polish SPI category is attractive for CEE market entry because Poland is the largest economy in Central and Eastern Europe — the sixth-largest economy in the EU by GDP. With 38 million people, a rapidly growing e-commerce sector, and strong mobile banking adoption (BLIK, Poland's instant mobile payment standard, has over 15 million users), Poland offers a substantial domestic market for payment startups.
The KNF registration process for SPIs is relatively streamlined compared to full EMI authorisation. The application requires a description of the proposed payment services, information about the business structure, details of planned AML/KYC procedures, and personal information on shareholders and directors. Capital requirements are nil, but the firm must demonstrate it has adequate operational resources to run compliantly.
Poland's fintech ecosystem is centred on Warsaw, which has attracted significant investment and talent from across the CEE region. The KNF has been proactive in developing fintech-friendly guidance and operates an Innovation Hub for dialogue with new entrants. For firms planning a CEE payment strategy, a Polish KNF registration can serve as both a domestic operating base and a proof-of-concept before seeking full EU EMI authorisation.
KNF Requirements & AML Compliance
Polish SPIs must comply with Poland's AML Act (Ustawa o przeciwdziałaniu praniu pieniędzy), which implements AMLD5 into Polish law. AML obligations include: appointing a compliance officer, implementing KYC/CDD procedures, conducting ongoing transaction monitoring, and filing suspicious transaction reports to GIIF (Generalny Inspektor Informacji Finansowej).
Why Poland? Largest CEE Economy
Poland has the sixth-largest economy in the EU and the largest in Central and Eastern Europe. E-commerce revenue exceeds €20 billion annually, with continued double-digit growth. Polish consumers are highly digitally engaged — mobile payment penetration is among the highest in Europe, driven by BLIK, the domestic instant mobile payment system integrated into virtually every Polish bank app.
The CEE region as a whole — Poland, Czech Republic, Slovakia, Hungary, Romania, Bulgaria — represents a combined market of over 80 million people with payment infrastructure that is becoming increasingly interconnected. A Polish SPI provides a base for understanding CEE payment dynamics, building local banking relationships, and demonstrating regulatory compliance before scaling to a full EMI covering the entire EU.
Warsaw is also emerging as a significant tech and fintech hub. Lower operating costs than Western European capitals, a large pool of engineering talent, and proximity to major EU markets make Poland an operationally attractive base for payment companies targeting CEE and beyond.
