# RFID Interlock (Web enabled)

> RFID Interlock (Web enabled)

Original author: rena (source: https://willbradley.name/2012/01/12/rfid-interlock-web-enabled/)

## Components

- **Arduino board** x 1
- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Article

This is a stripped-down version of the 23b hackerspace's Open Access Control system, intended for embedded use with an RFID reader and Ethernet shield for authenticating Wiegand RFID cards with a webservice. For code, schematics and circuitry, check out?<https://github.com/zyphlar/open-access-control-minimal-http>**WARNING, there is an error in the circuitry here. One of the pins from the shift register isn’t going to the LCD screen as intended. **The webserver component isn’t uploaded yet either; the interface simply relies on??a webserver (in the code at?<http://10.1.1.1/~access/access?id=YOURID&device=THISDEVICE>?) which returns ^username|OK$ when YOURID is a valid ID for accessing THISDEVICE. The username is then displayed on the LCD. **Original Link:?<https://willbradley.name/2012/01/12/rfid-interlock-web-enabled/>**
