Well, Google Image Charts, despite the notices that it was shutdown, appears to still work.

A QR code is a QR code, so it really doesn't matter how you generate it. The discussion forums indicate that www.image-charts.com/ is a drop in replacement for Google Image Charts. It does cost money though. There are also other free qr code api services such as goqr.me/api/

Hi Bruce,
I have downloaded the zip file for generating QR codes and it works perfect!
However, when I search for ways of generating QR codes on the web, there are a lot of articles telling that Google chart is deprecated and does not work any more. It was turned off March 25th 2019. Ref. developers.google.com/chart/image/docs/gallery/map_charts and news group .

Which version of Google chart is used in your example? According to the articles I have found online, the new substitution for Google Image Charts which is Google Charts, does not have any functionality for generating QR codes. So this does not make sense to me.


ls_chart_url = ' chart.apis.google.com/chart?cht=qr&chs= ' + String ( width ) + 'x' + String ( height ) + '&chl=' + ls_provision_url

Looking forward to hearing from you. Thanks!

Regards from Berit
