ID Cards
by Dave08
ID Cards is a Forge technology mod in which a player binds an ID card to a reader that triggers redstone based on a trust list.
What it does
Each ID card is bound to the player who holds it, and an ID card reader scans that owner against its trust list. When the scan matches, the reader produces a redstone signal, so doors, lamps or machines can be gated by card. A reader always accepts the person who placed it, and that owner can add other players to the reader's trust list through its interface, which is then accessible to everyone on it.
The mod is aimed at servers and LAN worlds that want a lightweight identification system without a large management framework. It is a single Forge build for 1.20.1 only, first published on 2025-04-29 and last updated on 2025-06-09. A server running it needs every connecting player to have it too. The author is a solo developer who notes that releases will come slowly and that the mechanisms are kept simple. The mod is under a custom license and is not open source, though its source code is public.
Key features
Bound ID cards
Each ID card is tied to its owner, so the reader checks who is holding the card rather than just the item.
Redstone output on match
A matching scan sends a redstone signal, letting a reader open doors or power machines.
Trust list on readers
A reader's trust list controls who it accepts, and players can add others to it through the reader.
Adjustable pulse length
A configurable box sets how long the reader's redstone pulse lasts after an accepted ID card.

How it compares
Bank Card Mod is a Forge mod for 1.20.1 under the MIT License, client and server, and it is not open source. SCP: Total Containment is also Forge for 1.20.1 and client and server, but it is under CC-BY-SA-3.0 and not open source. AE Dynamics is Forge for 1.20.1 – 1.20.6, client and server, and is open source under the MIT License, so it covers a wider version range than ID Cards.
