+- **Inventory Cloning**: Clone your own cards
+
+### 4. Integration with Existing Systems
+- **Lock System**: Extends unlock-system.js with 'rfid' case
+- **Minigame Framework**: Uses base-minigame.js foundation
+- **Ink Conversations**: New tag for triggering clone mode
+- **Inventory System**: Clickable keycards trigger cloning
+
+## Technical Specifications
+
+### RFID Card Data Structure
+```javascript
+{
+  type: "keycard",
+  name: "CEO Keycard",
+  key_id: "ceo_keycard",           // Matches lock's "requires"
+  rfid_hex: "4AC5EF44DC",           // 5-byte hex ID
+  rfid_facility: 239,               // Facility code (0-255)
+  rfid_card_number: 17628,          // Card number
+  rfid_protocol: "EM4100"           // Protocol type
+}
+```
+
+### RFID Cloner Data Structure
+```javascript
+{
+  type: "rfid_cloner",
+  name: "RFID Cloner",
+  saved_cards: [
+    {
+      name: "Security Officer",
+      hex: "4AC5EF44DC",
+      facility: 239,
+      card_number: 17628,
+      protocol: "EM4100",
+      cloned_at: "2024-01-15T10:30:00Z"
+    }
+  ]
+}
+```
+
+### RFID Lock Definition
+```json
+{
+  "room_server": {
+    "locked": true,
+    "lockType": "rfid",
+    "requires": "ceo_keycard"
+  }
+}
+```
+
+## Implementation Benefits
+
+### For Game Design
+- **New Puzzle Type**: Social engineering (clone NPC cards)
+- **Stealth Mechanic**: Secretly clone cards without detection
+- **Tech Realism**: Authentic hacking tool experience
+- **Progressive Challenge**: Start with cards, upgrade to cloner
+
+### For Players

+- **Collection**: Collect and organize cloned cards
+
+### For Story
+- **Mission Variety**: Infiltration missions requiring card cloning
+- **Character Interaction**: NPCs with different access levels
+- **Escalation**: Low-level cards → Clone higher access
+- **Consequences**: Using wrong card could trigger alarms
+
+## Alignment with Existing Systems
+
+### Similar to Keys/Pintumbler
+- **Lock Type**: Same pattern as "key" lock type
+- **Item Matching**: key_id matches requires field
+- **Minigame**: Same framework as lockpicking minigame
+- **Success Flow**: Same unlock callback pattern
+
+### Differences
+- **No Lockpicking**: Can't pick RFID locks (unlike key locks)
+- **Cloning Mechanic**: Unique to RFID system
+- **Digital Data**: Hex IDs instead of physical pin heights
+- **Inventory Interaction**: Clicking cards triggers cloning
+
+## Success Criteria

+
+## 🐛 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

+## 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

+RFID Keycard System - Placeholder Asset Editing Instructions
+=============================================================
+
+The placeholder assets have been created by copying existing sprites.
+They now need to be edited to match the specifications.
+
+KEYCARDS (assets/objects/keycard*.png)
+---------------------------------------
+Current: Copy of key.png
+Needs:
+  1. Rectangular card shape (32x48px)
+  2. Rounded corners (2-3px radius)
+  3. Small RFID chip graphic (8x8px gold square in upper-right)
+  4. Color variants:
+     - keycard.png: Gray/white (#CCCCCC)
+     - keycard-ceo.png: Gold (#FFD700)
+     - keycard-security.png: Blue (#4169E1)
+     - keycard-maintenance.png: Green (#32CD32)
+
+Tools: GIMP, Photoshop, Paint.NET, or Photopea (online)
+
+RFID CLONER (assets/objects/rfid_cloner.png)
+---------------------------------------------
+Current: Copy of bluetooth_scanner.png or phone.png
+Needs:
+  1. More rectangular device shape (48x48px)
+  2. Orange accent color (#FF8200)
+  3. Small black screen in upper portion
+  4. Flipper Zero-inspired design
+  5. Optional: Small antenna or wave indication
+
+Reference: Google "Flipper Zero" for design inspiration
+
+ICONS (assets/icons/)
+--------------------
+Current: Copy of signal.png
+Needs:
+  rfid-icon.png (24x24px):
+    - Simple RFID wave symbol (3 curved lines)
+    - Monochrome white or orange
+
+  nfc-waves.png (32x32px):
+    - Concentric circles or radio waves
+    - Orange color (#FF8200)
+
+These can be very simple - clarity at small size is key.
+
+OPTIONAL: Create final professional assets
+-------------------------------------------
+The placeholders will work for development and testing.
+For final release, consider:
+  - Hiring a pixel artist
+  - Using asset creation tools (Aseprite, Pyxel Edit)
+  - Commissioning custom sprites
+
+COLOR PALETTE REFERENCE
