## 📋 What Was Planned

### Feature Scope

#### 🔐 New Lock Type: RFID
- Works like existing lock types (key, pin, password, etc.)
- Requires matching keycard or emulated card
- Integrates with unlock-system.js

#### 🎴 New Items
1. **Keycard** - Physical RFID access cards
   - Unique hex IDs (e.g., "4AC5EF44DC")
   - Facility codes and card numbers
   - Multiple variants (CEO, Security, Maintenance)

2. **RFID Cloner** - Flipper Zero-inspired device
   - Saves cloned card data
   - Emulates saved cards
   - Persistent storage across game sessions

#### 🎮 New Minigame: RFIDMinigame
**Two Modes**:

1. **Unlock Mode**
   - Tap physical keycard to unlock
   - Navigate to saved cards
   - Emulate cloned cards
   - Flipper Zero UI with breadcrumbs

2. **Clone Mode**
   - Reading animation (2.5 seconds)
   - Display EM4100 card data
   - Save to cloner memory
   - Triggered from Ink or inventory

#### 🗣️ Ink Conversation Integration
New tag: `# clone_keycard:Card Name|HEX_ID`
- Enables social engineering gameplay
- Secretly clone NPC badges during conversations
- Example: `# clone_keycard:CEO|ABCDEF0123`

#### 📦 Inventory Integration
- Click keycards in inventory to clone them
- Requires RFID cloner in inventory
- One-click workflow

## 🎓 Learning Resources

### Flipper Zero

- Documentation: https://docs.flipperzero.one/
- RFID section: https://docs.flipperzero.one/rfid

### RFID Technology
- EM4100 protocol: 125kHz RFID standard
- Wiegand format: Common access control format
- DEZ format: Decimal representation of card IDs

### Game Development Patterns
- Minigame framework: See existing minigames in `js/minigames/`
- Lock system: See `js/systems/unlock-system.js`
- Ink tags: See `js/minigames/helpers/chat-helpers.js`

## 🐛 Known Considerations

### Potential Challenges
1. **CSS Complexity**: Flipper Zero UI may require iteration
   - Mitigation: Start simple, refine later
   - Fallback: Simplified UI if needed

2. **Animation Performance**: Reading animation must be smooth
   - Mitigation: Test early, use CSS transforms
   - Fallback: Reduce animation complexity

3. **Hex ID Validation**: Ensure hex IDs are valid
   - Mitigation: Add validation in RFIDDataManager
   - Fallback: Generate valid IDs automatically

4. **Duplicate Cards**: Handle saving same card multiple times
   - Mitigation: Check for duplicates before saving
   - Solution: Overwrite or prevent duplicate

### Design Decisions to Confirm
- [ ] Should cards have expiration/deactivation?
- [ ] Should cloner have limited storage?
- [ ] Should cloning have a success rate (not always 100%)?
- [ ] Should NPCs detect cloning attempts?
- [ ] Should there be multiple RFID protocols (not just EM4100)?

**Recommendation**: Implement basic version first, add complexity later
