Payment Network Architecture
Direct access to payment networks can be costly. Financial service providers (Gateways) facilitate access by allowing businesses to connect through their infrastructure.
Understand the technical architecture, access requirements, and infrastructure that powers modern payment rails. From gateways to network protocols.
A payment represents a transfer of value from one party to another in exchange for goods, services, or to fulfill financial obligations. Payment networks are the infrastructure that enables these two parties to communicate and transfer value securely.
Consider your phone plan with your carrier. Phone companies build cell towers and maintain an infrastructure of interconnected transmitters and receivers that allow us to make a phone call to another person. Just as there are many different phone carriers, there are numerous different payment networks.
Direct access to payment networks can be costly. Financial service providers (Gateways) facilitate access by allowing businesses to connect through their infrastructure.
Used when commercial businesses participate in payments. While consumers can access these networks, they're optimized for business transactions.
Proprietary systems controlled by network providers. Merchants must register with network providers to receive payments. Often require gateway access.
Emerging networks that eliminate middlemen by requiring both parties to be on the same network. Typically require accounts with the network provider.
Network-issued unique identifiers, account numbers, and access credentials
Funds held at approved financial institutions or digital assets in compatible wallets
Adherence to network rules, regulations, and technical specifications
Direct network access or connection through approved financial service providers
API connections, message formats, and protocol implementations
