Acquirer
Bank processing payments for merchant.
Why it matters
Acquirers matter because they influence merchant onboarding, transaction routing, settlement, dispute evidence, chargeback handling, risk monitoring, and the commercial terms of card acceptance.
How it works
Operationally, the merchant sends the transaction through its gateway or processor, the acquiring side forwards the request into the network, the issuer responds, and successful transactions later move through clearing and settlement back toward the merchant.
Risks and pitfalls
The common pitfall is to treat the acquirer as just another processor. The acquirer relationship usually carries merchant acceptance risk, scheme obligations, settlement responsibilities, and dispute obligations.
Regional notes
In BIST/MOEX/global analysis, acquiring should be separated from local bank licensing, cross-border acquiring, payment facilitator sponsorship, FX settlement, and the merchant’s regional card mix.
