Most people know the company that gives them a card.
Far fewer think about the company that helps a business accept that card. That is where acquiring comes in.
Behind every card payment sits a lot of work most customers never see: merchant onboarding, risk checks, fraud prevention, chargebacks, compliance, settlement, and ongoing monitoring.
In our latest interview, Jekaterina Romanova, Head of Acquiring at Wallester, explains what that looks like in practice after more than a decade working in card payments, e-commerce risk, and merchant supervision.
We spoke with her about why merchant risk is rarely black and white, how fraud has shifted from attacking payment systems to attacking people, and why risk management does not stop once a merchant is approved.
A useful look at the merchant side of card payments and the work that happens behind the checkout page.

Legend has it that the Earl of Sandwich invented this dish so he wouldn’t have to leave the gaming table to eat 🥪
At Wallester, we’ve taken that same ‘stay in the game’ spirit and optimised it for 2026. We’ve updated our office stack with a new ‘sub’ contractor – Sanga Sandwich Bar.
🐔 Caesar Chicken – A warm, panko-fried architecture with 24-month parmesan
🇮🇹 Italian Cold Cuts – A fusion of salami, peppers, and mustard that hits every layer
🍆 Roasted Eggplant – A balsamic-glazed masterpiece with fresh basil
