What is This Feature?

The RFID Keycard Lock System adds a new lock type to BreakEscape inspired by the Flipper Zero device. Players can:

1. Use physical keycards to unlock RFID-protected doors
2. Clone keycards using an RFID cloner device (Flipper Zero-style interface)
3. Emulate saved cards to unlock doors without the physical card
4. Secretly clone NPC badges during conversations for social engineering gameplay

---

Feature Highlights

🎮 Realistic Flipper Zero Interface

• Authentic monospace display
• Orange and black color scheme
• Navigation breadcrumbs (RFID > Saved > Emulate)
• Card reading animations
• EM4100 RFID protocol support

🔐 Two Gameplay Modes

Unlock Mode: Tap a keycard or emulate a saved card to open doors Clone Mode: Read and save RFID card data from NPCs or your own cards

🗣️ Ink Conversation Integration

New tag: # clone_keycard:Card Name|HEX_ID Allows stealthy card cloning during NPC conversations

📦 Inventory Integration

Click keycards in inventory to clone them (requires RFID cloner)

Key Design Decisions

Why Flipper Zero?

• Recognizable: Popular hacking tool, culturally relevant
• Authentic: Teaches real RFID concepts
• Fun: Satisfying UI to interact with
• Expandable: Can add more protocols later

Why EM4100 Protocol?

• Simple: 125kHz, easy to implement
• Common: Most access cards use this
• Realistic: Real-world standard
• Educational: Players learn actual RFID tech

Why Two Modes (Unlock vs Clone)?

• Flexibility: Multiple puzzle solutions
• Progression: Upgrade from cards to cloner
• Stealth: Social engineering gameplay
• Realism: Matches real-world RFID usage

Ink Conversation

=== talk_to_ceo ===
# speaker:npc
Hello, what can I do for you?

* [Ask about server access]
  # speaker:npc
  I have the server keycard, but I can't give it to you.
  -> hub

* [Secretly clone their keycard]
  # clone_keycard:CEO Keycard|ABCDEF0123
  # speaker:player
  *Subtly scans their badge*
  # speaker:npc
  Is something wrong?
  -> hub
