Front & Rear Camera Scanning Settings
Use the iPad's front & rear cameras to scan and interpret specific types of barcodes, including UPC and QR codes.
In this article
Camera
Supported in:
Choose whether to use the front or rear camera for scanning. The rear camera features a higher resolution camera, which may provide more reliable scanning results than the front camera.
Default Value:
- None
Other Possible Values:
- Front
- Back
We've added custom JavaScript functions that you can call to begin the scan, at which point the camera goes full-screen allowing the visitor to easily position the code for scanning. When the scan had been captured, the data from the barcode is returned to your page through a JavaScript callback.
More information and sample code demonstrating these functions are available here.

Supported Codes
Supported in:
Control the type of barcode scanning your visitors can perform.
Default Value:
- All
Other Possible Values:
- QR codes only
- UPC barcodes only
- Interleaved 2 of 5
The "All" option includes the following codes:
- EAN-2, GS1 2-digit add-on
- EAN-5, GS1 5-digit add-on
- EAN-8
- EAN-13
- UPC-A
- UPC-E
- ISBN-10 (from EAN-13)
- ISBN-13 (from EAN-13)
- EAN/UPC composite
- GS1 DataBar (RSS)
- GS1 DataBar Expanded
- Code 39
- Code 93
- Code 128
- QR Code
Other options include "QR codes only", "UPC barcodes only", and "Interleaved 2 of 5". Using these narrower categories may decrease the amount of time it takes the app to interpret and return barcode data.
Note: "Interleaved 2 of 5" is not supported as a part of "All" due to default behavior of the underlying ZBar library Kiosk Pro uses for scanning. ZBar turns off support for Interleaved 2 of 5 to improve scanning time for other barcode types.

Scan Area
Supported in:
Define how much of the camera overlay can be used for scanning when using the JavaScript API. The scan area is outlined on screen with a blue rectangular overlay.
Scan area is defined as a set of four coordinates: leftCorner, topCorner, width, height. These are expressed as a decimal percentage of the screen where 0 = 0% and 1 = 100%.
Default Value: 0, 0, 1, 1
The default value of "0, 0, 1, 1", uses the full camera overlay. A value of "0.25, 0.25, 0.5, 0.5" would allow scanning in a rectangular area that covered the center 50% of the screen.
Values for Remote Settings Control & Managed App Configuration
| Key | kp_zscanner_scanArea |
|---|---|
| Key Type | string |
| Default Value | 0,0,1,1 |
