Cross-Border Transfers

Visa and MasterCard bolster Poland’s international connectivity through efficient cross-border transfer services. These services include international card payments, online remittances, and SWIFT-based transfers. For example, Polish consumers can make international purchases or send funds abroad with competitive currency conversion rates and low fees, thanks to partnerships with global institutions. Furthermore, the expansion of digital wallets and integrated crypto platforms enhances cross-border flexibility, catering to the increasingly globalized Polish market.

Mobile & Online Banking

Modern banking in Poland relies heavily on mobile and online platforms integrated with Visa/MasterCard services. Leading banks provide user-friendly apps that allow customers to manage their accounts, make payments, set up recurring transfers, and monitor transactions in real-time.
