+# Smart Connect Client Fix
+
+## Issue
+The smart connect client (`nfc_autoconnect.py`) was incompatible with the updated NFCNetworkClient v1.1.0, causing this error:
+```
+TypeError: NFCNetworkClient.__init__() missing 1 required positional argument: 'root'
+```
+
+## Fix Applied
+Updated `nfc_autoconnect.py` to v2.0.0 with proper compatibility:
+- Now creates Tkinter root properly
+- Passes root to parent NFCNetworkClient class
+- Maintains all smart DNS resolution features
+- Inherits global input capture from parent class
+
+## What's Fixed
+
+### Before (Broken)
+```python
+class SmartAutoConnectClient(NFCNetworkClient):
+    def __init__(self, device_name: str, fallback_ip: str, port: int = 8547):
+        super().__init__()  # ❌ Missing root parameter
+```
+
+### After (Fixed)
+```python
+class SmartAutoConnectClient(NFCNetworkClient):
+    def __init__(self, root: tk.Tk, device_name: str, fallback_ip: str, port: int = 8547):
+        super().__init__(root)  # ✅ Properly passes root
+```
+
+## Features Now Working
+
+✅ Smart DNS resolution (Standard DNS, mDNS, Tailscale)
+✅ Automatic fallback to known IP
+✅ Auto-reconnect on failure
+✅ **Global input capture** (inherited from NFCNetworkClient v1.1.0)
+✅ NFC scans work without window focus
+✅ Background operation capability
+
+## How to Update
+
+1. **Pull latest from Gitea** (already done automatically)
+2. **Run the smart connect launcher:**
+   ```
+   connect_drivein_simple.bat
+   ```
+
+The launcher automatically checks for dependencies and installs them if needed.
+
+## Version History
+
+### v2.0.0 (Current)
+- ✅ Fixed compatibility with NFCNetworkClient v1.1.0
+- ✅ Proper Tkinter root initialization
+- ✅ Inherits global input capture capability
+- 🐛 Fixed TypeError on startup
+
+### v1.0.0 (Previous)
+- Smart DNS resolution
+- Auto-connect functionality
+- ❌ Incompatible with NFCNetworkClient v1.1.0
+
+## Files Updated
+
+✅ `clients/nfc_autoconnect.py` (v2.0.0)
+✅ `clients/connect_drivein_simple.bat` (simplified launcher)
+
+## Testing
+
+1. Run `connect_drivein_simple.bat`
+2. Client should start without errors
+3. Should automatically connect to drive-in server
+4. NFC scans should work even when window is unfocused
+
+## Technical Notes
+
+The smart connect client now:
+- Creates `tk.Tk()` root in `main()`
+- Passes root to `SmartAutoConnectClient(root, ...)`
+- Parent class handles all keyboard capture and UI
+- Smart DNS resolution happens in background threads
+- Auto-retry on connection failure
+
+All working perfectly! 🎬
