Create Unique Card
by Takkkom
Create Unique Card gives Create's Redstone Links a one-of-a-kind UUID so that links on a network cannot be cross-wired by mistake.
What it does
The add-on introduces the Unique Card, an encrypted item that assigns each link its own UUID. Two links that share a frequency still stay separate, which keeps channels from interfering with one another. Because each pairing is a dedicated one-to-one secure line, a player can build a wireless network without worrying about a neighbor's signal reaching their machines.
Large automation factories and multiplayer servers are the main setting for the mod. Players with heavy factories often run into frequency shortages and the limits of two-slot item combinations, and the card removes that pressure by giving every link its own identity. Server administrators can rely on it for a more secure wireless setup. Create Unique Card needs Create to run, and it is published for NeoForge only, with a single file, 1.0.0 for 1.21.1, dated 2026-06-18. The environment is client and server, so the server and every player need the mod, and the code is released under the MIT License as open source.
Key features
Unique Card item
An encrypted card carries a one-of-a-kind UUID that identifies a single link pairing.
Cross-wiring prevention
Links with matching frequencies stay on separate channels, so signals do not mix between networks.
One-to-one secure lines
Each pairing forms a dedicated wireless connection between exactly two links.
Frequency relief
Factories can run more links without stretching the standard frequency slots and their item combinations.
