What is OpenDoorSim?

OpenDoorSim (ODS) is a personal, open-source RFID lab designed for ease of use and wide compatibility. It simulates Physical Access Control Systems (PACS) by connecting to real readers, so you can hack (or defend) the real thing! All iterations of OpenDoorSim are based on the same ODS board. With ODS, at-home experiments, big CTFs, hands-on workshops, banger demos and advanced research are a breeze. It works with any Wiegand or (soon) OSDP reader, and fits easily in your bag. Sporting a fresh web UI with a mirrored virtual display, an on-device hardware menu, and multiple modes to make life easy, you may find it hard to put down…

Key Features

Easy To Use

The world’s friendliest RFID lab is a breeze to use — run CTFs, demos, research, workshops, and more via hardware or web interfaces! All you need to start is the board!

Multi Mode

Investigate binary messages in RAW mode. Or, switch to USER mode to manage, grant and deny access to specific credentials. Want to go stealth? We’ve got settings for that too.

Open Hardware Design

Schematics, 3D Print STLs, Gerbers, and more released under open licenses. Fabricate, modify, and iterate to your heart’s content. Create your own modules for the integrated module slots!

Open Source Software

Created and maintained by a worldwide community. We are always looking to improve and develop the project. Updates, issues, and feature requests happen all on GitHub.

Modular Assembly

Frame, electronics, and software are decoupled layers. Upgrade or replace without rebuilding the whole rig. Parts are easy to source — either buy off the shelf or manufacture them yourself!

Community Driven

There are tons of ways to support the project and community — build your own ODS board, run a CTF, contribute features, tell your friends, or buy an official supporter kit!

Who It’s For

OpenDoorSim is built for anyone who needs an RFID / PACS lab:
  • Vulnerability Researchers who want a quick and easy way to set up, research, and demo their findings.
  • Students looking to learn about RFID, card and reader vulnerabilities, and physical security.
  • CTF Organizers who want a turnkey, interactive solution for RFID / PACS challenges.
  • Industry Professionals who want to test equipment, validate configurations, and demo their RFID cards and readers, .
  • Hobbyists & Makers who want a satisfying weekend build that interacts with real world RFID hardware.
If you can turn a screwdriver, use a soldering iron, and run a terminal, you have everything you need to get started.
