ID Tech, the manufacturer, uses a “Universal SDK” that exposes a common API across all of its supported products. The SDK has several flavors that vary by the operating system you will deploy on and the language you’ll use. It supports iOS, Android, Windows, and Linux.
For more information on the SDK, see the VP3300 technical product page.


To pair the VP3300 with an Android device, you must navigate to the Bluetooth Settings in the Android Device. Ensure the VP3300 is turned on. It will appear in available devices as “IDTECH:VP3300-...”
When using an iOS device, you can connect to the VP3300 directly from the Cardknox Mobile App. If Bluetooth is not enabled, you’ll receive an indicator for enabling Bluetooth on the device.
Once Bluetooth is enabled, you’ll see a Scanning message. In order to connect, tap the bluetooth button on the VP3300 device to complete the connection.
