I think right now, any keycard created can open any keycard reader. That's kind of a security breach! If you could make it to where the keycards are paired with a keycard reader, that would be great.

Hi there! That's a real security breach. Please add pairing keycards to readers. Or u may modify whitelist module for keycard reader, so player would be able to open it only at BOTH circumstances: 1) He has required level keycard and 2) He is in whitelist. If whitelist module isn't installed - it would be enough for player just to use required level keycard, as usual as it's today's version of securitycraft. I love this mod and playing it with my friends at 14.4.4, hope to see an update, thanks)

Same here, but I think you shouldn't add the whitelist condition, or it would be smarter to use a keypad (More resourcce-friendly)
