Key points

  • Definition: Card Network connects issuers and acquirers under network technical and operating rules and is not the issuing bank.
  • Flow position: The acquiring side establishes merchant acceptance and submits transactions into a card network.
  • Do not confuse: Card Network / Acquiring Bank

How it fits into the payment flow

For Card Network, the relevant process is as follows: The acquiring side establishes merchant acceptance and submits transactions into a card network. The network defines messaging, routing, and rules between acquirers and issuers. BIN sponsorship is a program and network-access arrangement, not an acquiring function.

A practical review of Card Network should account for this: one company may supply acquiring, processing, and gateway services, but the contractual roles remain distinct. Troubleshooting should locate the issue at merchant integration, acquiring processing, network routing, or the issuer decision.

Practical example

A card network routes an acquiring-side authorization message to the relevant issuer side and maintains operating rules. It connects the parties without usually holding the consumer's deposit account.
