API: Scan Using Aila Scanners

Return data from a scan through a connected Aila scanner, as well as return information about the status and configuration of the scanner.

Supported barcode types for this integration include UPC-EAN, QR, Code 128, Code 39, PDF417, and Interleaved 2 of 5.  Aila's scanners use a mirrored system to access the rear camera on the iPad for barcode capture and recognition and the audio jack or USB-C port for communication with the app.

It is possible to configure the scanning mode, motion detection mode, whether the scanner should beep when a scan is recognized, and which types of codes should be returned in the app's settings.

Triggers via API Functions

Start Scanning

This function starts a new scanning session.

Triggers Kiosk Pro will immediately trigger kp_padlockScan_scanningStateDidChange with the current scanning status.

Stop Scanning

This function ends any scanning session currently in progress.

Triggers Kiosk Pro will immediately trigger kp_padlockScan_scanningStateDidChange with the current scanning status.

Check Scanning Status

This function triggers a callback to return the scanning status of the Alia scanner currently connected.

Triggers Kiosk Pro will immediately trigger kp_padlockScan_scanningStateDidChange with the current scanning status.


This function triggers an audible alert beep from the scanner unit. It is also possible to trigger a beep automatically following a successful scan using the Automatically Beep on Scan setting.


Check Hardware Class

This function triggers a callback which returns which type of Alia scanner is currently connected.

Triggers Kiosk Pro will immediately call kp_padlockScan_hardwareClassDidChange with the current status.

Check SDK Version

This function triggers a callback with the current SDK version of the connected Aila scanner.

Parameters callback - [string] the name of the callback to be triggered with the result
Callback format
Callback return values versionString - [string] the SDK version associated with the Aila scanner currently connected

Notifications via API Callbacks

When a Scan is Returned

This callback is triggered whenever the scanner complete a successful scan.

If source image contains a valid code, but the code does not match a supported type of code (as defined in Kiosk Pro settings) or if the source image does not contain a valid code, then this callback will not be triggered and the scan will be ignored.

kp_padlockScan_scanningDidFinish(scanType, scanData);
Return values
  • scanType - [integer] representing the type of bar code scanned. Possible values are:
    • 1 - UPC-EAN
    • 2 - QR Code
    • 4 - Code 128
    • 8 - Code 39
    • 16 - Interleaved 2 of 5
  • scanData - [string] the data contained in the barcode scanned

When Scanning Status Changes

This callback is triggered when the connected scanner is powered on or off through calls in the API or any time ' kp_padlockScan_getScanningState' is called.

Return values
  • scanning - [integer] representing the current scanning status of the connected scanner. Possible values are:
    • 1 - a scanning session is ongoing
    • 0 - not scanning

When Hardware Class Changes

This callback is triggered when an Aila scanner is connected or any time ' kp_padlockScan_getHardwareClass' is called.

Return values
  • hardwareClass - [integer] the type of Aila hardware connected. Possible values are:
    • 0 - no scanner connected
    • 1 - kiosk scanner connected
    • 2 - hand-held, mobile scanner connected

Sample Code

  • This sample code relies on the JavaScript APIs built into Kiosk Pro and will not run successfully in other browsers or within our in-app help interface.
  • To run sample code, set the app's homepage to kioskgroup.com/aila-scanning-api
  • To download a .zip of sample code, click here.

Change Log

  • Added in version 8.0. Ability to return the firmware version of the scanner added in 9.5.7
