QR Code/Barcode Scanner

This is some text inside of a div block.

This article explains the features of the Code Scanner (QR Code/Barcode Scanner) block and how it can be used to design your app.

Code Scanner Block is used for:

  1. Scanning QR Codes/Barcodes from any place and entering them into a form.
  2. No-touch attendance systems.

Editing the Code Scanner block

Click on the block and configure it by editing on the right panel.

Label

The label is the name of the block that the end user sees in the app.

Example: Scan the Product ID

Description

The description is the additional information provided to the end user which will be displayed below the input area.

Allow user to input manually

Enabling this option will allow the user to enter the QR Code or the barcode manually, without scanning. This becomes important when the codes are not scannable or distorted.

Disable this option if you do not want the users to modify the codes that are scanned by the camera.

Display this field if

Use this if you want to show or hide a field under certain conditions. It accepts the standard Clappia Formulae, similar to conditional sections.

  2. Using these variables you can write Excel-like formulae.

Example: When the user enters the employee name then the Scan field is displayed and will be accessible to use.

Allow value to be changed after initial submission

This option is enabled by default. End users can edit the value entered in this field after creating a submission. Disable it if you do not want the end users to edit the submitted value.
