This question type is available for the App-based products - AskMe and CAPI - and is intended to be used on a device with a camera. Note that it is only available when a responsive rendering layout is used. Users may for example need to conduct an audit of brands in a store, and this question type records and interprets barcodes and QR codes.

The question details page for this item - allows you to set the input box size. The properties available for this question type are described in the Question Properties documentation (go to Accessing Question Properties for more information).

In the event the user is not satisfied with the result, he/she can re-tap on the icon and take a new recording. The user can also enter a value manually if required. You can set a property in the question's property sheet to prevent the user from being able to input a value manually.
