RFID and Security

UBS RFID readers provide physical, server-authoritative access control for banks, shops, doors, and redstone targets.

RFID Scanner

Place the scanner against a vertical surface. Its reader face points toward the placing player. The scanner receives a new unique reader ID whenever a new block is placed; breaking and replacing it does not preserve the former identity.

Shift-right-click opens settings. The first owner sets a PIN; later configuration requires that PIN.

The tabbed UI supports:

• General: enabled state, access level 1..100, bank/shop link, normal/forced-open/forced-closed mode
• Signals: independent idle, success, and failure strengths and durations; failed-attempt threshold/reset
• Cards: write access to a held card, inspect authorized cards, revoke one card, scroll long lists
• Targets: choose exact success and failure blocks/faces within the allowed bank/shop premise

The scanner itself does not emit redstone. Only the selected target block/face receives the configured directed signal, avoiding accidental power to adjacent blocks.

RFID Cards

Cards contain their own unique card ID and can hold access grants for multiple readers. Writing one reader grant does not erase grants for other readers.

A scan succeeds only when:

• the reader is enabled and not forced closed
• the card includes this exact reader ID
• the grant meets the configured access level
• the card/reader authorization has not been revoked

Matching access level alone is not enough.

Door Passage

When a success target opens a supported door, authorization is tracked per player. The validated player can pass during the grant window; another player cannot simply follow through the opening. Passage checks work from either side of the protected door.

Modded doors can integrate using the heist/security door adapter surface where applicable.

Visual States

• Idle texture while waiting
• Success texture for the configured success duration
• Failure texture for the configured failure duration

Failed scans increment the reader attempt counter. At the configured threshold, failure targets activate and the counter resets.

RFID Spoofer

The RFID spoofer is a heist tool. During a valid active heist it attempts to compromise a scanner and activate its configured success targets. It does not permanently write a legitimate card grant and remains subject to heist target/premise validation.

Security Guidance

• Use different reader IDs for separate secure areas.
• Revoke lost card IDs instead of only lowering the reader level.
• Keep signal targets inside the protected premise.
• Use short success windows for public corridors.
• Review Safe Access/door logs after an alarm.
