Integrating biometric authentication, such as fingerprint scanning or facial recognition, enhances wallet security and user convenience. To start, use the biometric authentication APIs provided by iOS and Android, such as Face ID or Touch ID for mobile apps. For Android, Google’s BiometricPrompt API is ideal, while iOS uses LocalAuthentication Framework. These APIs securely access the device's biometric sensors, ensuring that only the authorized user can access the wallet. You can implement this as a second layer of authentication after the user enters their PIN or password, further reducing the risk of unauthorized access. Be mindful of data privacy and compliance regulations (e.g., GDPR) when storing and handling biometric data. Always ensure that biometric data is processed and stored locally on the device for maximum security, without transmitting sensitive information over the internet.
