Read explanationUnderstanding Digital Money Flow
Digital money doesn't move instantly like physical cash. Every payment — whether UPI, card, or bank transfer — involves multiple systems: banking servers, payment networks, security checks, and settlement processes.
Delays like "pending" status, transaction failures, or interest calculations are normal system behaviors, not errors. They happen because banks need to verify, secure, and settle each transaction across different institutions.
To understand the technical infrastructure behind these banking systems — the servers, networks, and apps that make digital payments possible — explore Technology Explained. For insights into how payment apps interact with networks and servers, visit Internet & Apps.
