Had to look it up myself

Wero is a European mobile payment system that should replace Giropay in Germany, Paylib in France,[1] Payconiq in Belgium[2] and Luxembourg, and iDEAL in the Netherlands. The service was launched on 2 July 2024 by the European Payments Initiative.[3] The service competes with PayPal, credit cards and similar services. It started as a real-time payment system in 2024, and from summer 2025 extended online payment functions were added on a step-by-step basis.

Looks like it's an effort to standardise all the local versions of the same payment systems, which seem to be P2P mobile money transfer and payment systems
