QR Code Assignment Guide


This guide is to help users assign unspecified QR Codes to equipment, location, or user tag.

Note: Before users are able to use Tango™ Mobile, users must have a barcode scanner installed on their SmartPhone or Tablet. Some devices may already have this type of application installed, other will have to download one from an App Store. For this tutorial, we are using ZXing ("Zebra Crossing") which is available for Android and Apple products.

Important:All QR Codes have to be entered into 24/7 Systems, Inc. databases before they can be associated with the Users Database, contact us for more information.

To assign a QR code, scan an unassigned QR code with a Smart Phone or Tablet.

Once users have scanned the QR code, users may be prompted to choose a course of action, choose "Open Browser" or the equivalent. This will bring the users to a login screen which will require their Tango™ username and password. Note: User must have "Location Edit Users" rights to assign QR Codes.
