Hungary saw its first live, authenticated AI-agent payment in May through OTP Bank and Mastercard, followed by a SimplePay and FinTechZone webinar on agentic payments. For merchants, the key question is not whether robots will pay at the till tomorrow. It is whether your webshop, booking flow and payment provider will be visible, secure and competitive in AI-led buying journeys.

According to the latest MNB payment statistics release, card purchase value in Hungary grew by 19% year-on-year in Q4 2025, while transaction count increased by 7.7%. This is not a sudden shift, but the latest data point in a long-running payment trend: merchants now need to optimise cost, online wallet payments and checkout conversion.

The interchange fee is the largest cost component of every card transaction. We explain how it works, the EU cap, and when it really matters for your merchant costs.

We are living in the golden age of online shopping, yet the payment process often still feels like the past: rummaging for bank cards, typing out 16-digit numbers, and transactions interrupted by typos. This is the universal, global solution offered by the joint technology of Mastercard and Visa: Click to Pay.

Interchange++ pricing breaks down into 3 fees: interchange + card scheme + acquirer margin. We explain clearly when it makes sense, how to compare offers, and when to choose blended pricing instead — with 2026 examples and decision-making guidance.
