      Hello Mayur,

      Powershell or any other script will on help you creating a static QR Code. If you want to know the location of each scan you you will need to request it from the user.

      This can be easily done using dynamic QR Codes which redirect the users through a page that takes care of collecting this data.

      Hello John,

      Yes, of course, you can use QR Codes in your restaurant in so many ways. Especially these days because of the COVID-19, when any contactless technologies and solutions are so helpful.

      Actually, we have published a post on this topic today: https://blog.qrd.by/2020/05/25/qr-code-restaurant-menus

      You are asking about offline methods. If you use static codes you will be missing out most of the possibilities that QR Codes have to offer.

      You will not have the ability to update the destination URL, use multimedia contents, or get any insights/analytics on what is going on with your QR Codes.
      https://blog.qrd.by/2016/03/03/static-versus-dynamic-qr-code/

      That said, if you still want to use offline QR Codes you will be limited to the amount of information you can fit into the QR Code, which is a lot, but the more text you type the harder it gets to read. You would also need a very large QR Code to fit, for example, your restaurant menu. And again, you would not be able to embed any image or format your content.

      Here you have an example of how an offline static QR Code menu would look like:
      

      You could also offer them the possibility to connect to your WIFI using a static QR Code. You can create one here for free:

      A QR Code management platform like ours allows you to create dynamic QR Codes and landing pages for different types and sizes of businesses. You are more than welcome to test it here: https://qrd.by/features

   Hi, is it possible to create a QR code to display a PDF without going via a URL?

      No, for two reasons:

      1. A QR Code can only encode up to 4296 chars.
      2. Even if you can create a PDF with less than 4296 chars there is no QR Code Reader that can decode a binary encoded PDF in a QR Code. There are various types like an URL, VCARD, WLAN, EVENT, GPS, etc. that can be decoded by a QR Code Reader, however there is no native PDF type.

            Hello Jay, we do not and will not support PDF417 barcodes. QR Codes can be read by almost any smartphone without using a third-party app. PDF417 are a proprietary format that is not recognized by people and it needs a special app to decode. Best Regards, Peter

   Hello this may sound weird but hear me out…..
   Is there a way to make an offline qr code to point to a static ip address? Long story short I host karaoke and have a remote server request service, I setup a wireless network with no Internet and I can get to this service by typing the 192.168.1.200 but I would like to have my clients scan a qr code without typing in this address everytime, as I understand an offline code cannot be changed hence the static ip address. I hope I gave enough detail and hope to get a quick response

      Hello, you can create a static QR Code with the URL http://192.168.1.200
      This URL will redirect the user to the karaoke landing page when they are connected to your WLAN.
      But you can use the same URL and create a dynamic QR Code with a human friendly readable URL e.g. https://qrd.by/karaoke -> http://192.168.1.200
      Let me know how it worked out for you,
      Best Regards,
      Peter
