Widget: QR Code Reader

The QR Code Reader widget provides a configurable button for scanning QR codes or barcodes with a system camera:

When users select the button, the system prompts them to grant camera access. They can then scan one or more codes in a full-screen camera view:

The widget stores scanned data in a Workshop variable. You can display the data in a Markdown widget, use it to look up objects through an Object Set variable, or use it to populate an Action form input.

Configuration options

Below are the core configuration options for the QR Code Reader:

  • Code Scanner Type: Configures whether the widget scans QR codes or barcodes.
    • QR Code Scanner: Scans standard QR codes.
    • Barcode Scanner: Scans barcodes. When this option is selected, you can configure which barcode formats to support using the Barcode Formats dropdown menu. Available formats include PDF417 and other common barcode types.
  • Single or multiple code: Configures whether the widget scans the first code it sees, or allows users to scan multiple codes in a row. If multiple code mode is selected, then the scanned data will be output as a string array variable. If single code is selected, then the scanned data is a string variable.
  • Should prompt user before scanning: When enabled, the user will be prompted to select a Scan code button to confirm that a code should be scanned. When disabled, any detected code will be scanned immediately.
  • Button configuration: Configuration options for the button used to open the full-screen code reader. This is identical to the configuration for an individual button in the Button Group Widget.
