      Can NoahFace be configured to display a QR Code?

      QR Codes

      The NoahFace App can be configured to display a QR Code as part of the user feedback. This allows you to direct users to a custom screen to collect additional information, passing temperature data to it.

      To display a QR code, just use feedback icon names with "qrcode" as the second feedback element (ie: "tickqrcode", "crossqrcode", or "tempqrcode"). For example:

       

      icons=tickqrcode;cross;redtherm

       

      To specify the URL to encode in the QR Code, specify the "qrcode" option. For example:

      qrcode=http://google.com?q=[ORG]

       

      You can place any of the following variables in your URL, surrounded by square brackets. Each variable will be substituted with its corresponding value:

      • TIME. The local time.
      • UTC. The universal time.
      • TEMP. The measured temperature.
      • ELEVATED. True for elevated temperatures, else false.
      • USERID. The identifier of the user, if known.
      • NUMBER. The number of the user, if known.
      • FIRST. The first name of the user, if known.
      • LAST. The last name of the user, if known.
      • PHONE. The phone number of the user, if known.
      • USERTYPE. The user type of the user, if known.
      • ORG. The name of the organisation.
      • SITE. The name of the site.
      • DEVICE. The name of the device.
      • DEVID. The identifier of the device.

      You can lengthen the default time that the user feedback is displayed by specifying the "ticktime", "crosstime", or "temptime". For example:

       

      ticktime=15

       

      To specify more than one option, just comma separate them. A complete example is:

       

      icons=tickqrcode, ticktime=15, hidereg=true, qrcode=http://google.com?q=[ORG], greeting=Scan the QR code to complete your registration.
