title: Google Charts API - QR Code
body: <p>I am using Google Charts API to generate QR code as referred in this link <a href="https://www.gregorystrike.com/2011/01/26/how-to-use-google-charts-api-to-generate-your-own-qr-code/" rel="nofollow noreferrer">https://www.gregorystrike.com/2011/01/26/how-to-use-google-charts-api-to-generate-your-own-qr-code/</a></p>
  
  <p>In this as the parameters are visible it seems to be insecure</p>
  
  <p>Users can change the values available in the parameters using developer tools like inspector element of Firefox. Is there a secure way to generate QR codes</p>
  
  <p>Thanks</p>
