RFC 6455
RFC 6455 - The WebSocket Protocol
Overview
Defines the WebSocket protocol, providing full-duplex bidirectional communication over a single TCP connection. The connection starts as an HTTP upgrade handshake and then switches to a lightweight framed protocol. Supports both text and binary message frames with minimal overhead (2-14 byte header).
Why it matters for RFID
Powers real-time RFID dashboards, live tag read streams, and reader management consoles in the browser. MCP (Model Context Protocol) servers also use WebSocket/SSE for communication.
