Payment gateway Definition.
The technical layer that carries the transaction from the merchant’s website or POS to the acquirer or processor, handling encryption, format conversion, and 3-D Secure orchestration. Unlike the acquirer, it never touches the funds and bears no financial risk. Modern PSPs bundle gateway, acquiring, and fraud prevention into a single offering.
