ESP RFID is an open-source access control system that runs on the ESP8266 microcontroller and supports MFRC522, PN532, RDM6300, and Wiegand RFID readers. It provides a web-based UI over WebSocket/JSON for managing up to 1,000 users, with NTP time sync and MQTT support for door access scenarios like maker spaces and labs.

Use cases

• build an RFID door lock for a maker space
• manage access control users via a web UI
• flash an ESP8266 to read RC522 or PN532 RFID tags
• log door access events with timestamps
• integrate RFID access events with MQTT
• use Wiegand readers with an ESP8266 access system

When to choose

• you want a cheap, self-hosted RFID access control system
• you use supported readers like RC522, PN532, RDM6300, or Wiegand
• you need a web UI for managing users without extra infrastructure
• you want open-source hardware and firmware you can tinker with

When to avoid

• you need enterprise-grade access control with auditing and compliance
• your hardware is not ESP8266-based or uses unsupported readers
• you need large-scale deployments beyond ~1,000 users per controller
• you require battery-powered or low-power operation
