Understanding Digital Payment Basics

What Is a Digital Payment?

A digital payment is any financial transaction where money is transferred electronically from one party to another. Unlike traditional cash transactions, digital payments exist entirely in the digital realm, processed through encrypted computer networks and sophisticated financial systems.

2. Payee: The recipient of the funds
3. Payment Instrument: The method used (e.g., mobile wallet, credit card)
4. Payment Processor: The service that validates and executes the transaction
5. Settlement System: The infrastructure that completes the money transfer
