Mobile ID SDK
The Mobile ID SDK is a library that lets you implement Mobile ID functionality in a custom app. The SDK enables mobile devices to act as secure credentials for access control, time & attendance, and or similar card-reading applications by transferring secure credentials via Bluetooth Low Energy (BLE) to readers.
Key features
- Cross-platform: Supporting both Android and iOS
- BLE-based: Uses Bluetooth Low Energy for communication with readers
- Secure: Cryptographic signed credentials transferred over AES128-GCM connection
- Automatic permission handling: SDK manages BLE permissions automatically
- Background operation: Supports background BLE advertising on iOS
- Built-in logging: Comprehensive logging allows BALTECH to support even complex problems
- Reactive APIs: APIs for modern reactive programming
Requirements
The SDK is available for XCode (Swift/Objective-C) and Android Studio (Kotlin/Java).
iOS:
- iOS 13.0+
- Physical device with BLE support (BLE not available in simulator)
Android:
- Android SDK 28+
- Device with BLE support
