Barcode questions allow the user to scan a barcode with the device's camera. This feature is supported on most, but not all, devices that have a fairly high resolution camera with auto-focus. If the camera on a mobile device does not have auto-focus capability, it is still possible to capture and decode barcodes; however, the user must manually place the camera and/or barcode so that is in focus.
An example of a Barcode question on an iOS device is shown below:
In the Form Builder, the Barcode question appears as shown below:
The Question Edit screen for the Barcode question type has three tabs: General, Properties, and Help Options. This article will go through each of the tabs.
The Unique ID is the reference for the question. For more information on Unique IDs, read: Overview: Unique IDs. It can either be auto-generated based on the question text, or customized.
Restrictions control how your mobile users interact with a question. They can be set on the question itself, or controlled by Conditional Logic.

Properties allow you to set up your question in various ways. The Barcode question type has simple properties, allowing you to specify which kind of barcode will be scanned. Where possible, specify the desired type of barcode in the Barcode Properties tab to aid the speed of barcode recognition.
Barcode Standards supported by ProntoForms are:
- UPC (A or E): Universal product code seen on almost all retail products in the USA and Canada.

Other types of barcodes are supported; they will simply take a moment longer to recognize.
Adding "Help" content to forms gives mobile users access to support and other resources out in the field. Help content is available to users through a button embedded beside a question. Any question in the form can include a link to Youtube videos, web pages, or HTML-formatted work instructions.
