# Skill: Native Module Integration
## When to load
When integrating device APIs, bridging to native SDKs, or debugging platform-specific behavior.
## When to Use Native Modules
```
Use Native Module:
- Device hardware (camera, accelerometer, NFC, Bluetooth)
- Cryptographic operations (device secure enclave)
- Computation-intensive tasks (image processing, on-device ML)
- Third-party SDKs without JS wrapper
Stay in JS/React Native:
- UI rendering and interactions
- Network requests
- State management
- Business logic not requiring device APIs
```
## Biometric Authentication
```typescript
import ReactNativeBiometrics from 'react-native-biometrics';
export async function authenticateWithBiometrics(): Promise<boolean> {
const rnBiometrics = new ReactNativeBiometrics({ allowDeviceCredentials: true });
const { biometryType } = await rnBiometrics.isSensorAvailable();
if (!biometryType) return authenticateWithPin();
const { success } = await rnBiometrics.simplePrompt({
promptMessage: biometryType === 'FaceID' ? 'Confirm with Face ID' : 'Confirm with fingerprint'
});
return success;
}
```
