Unique QR Code at each POST/PAGE/LISTING which represent it own permalink

Basically I am looking for a QR code plugin, which the QR code may appear as a widget in the listing.

The code will represent the listing permalink. Reason I would like to have this QR code because I would like to make convenience for example Visitor1 had favorite this listing, and Visitor1 would like to share this listing to Visitor2, Visitor2 can just scan the QR code from Visitor1 mobile phone/Computer and he/she can access to this listing

I am unable to find any relevant plugin, any one had any recommendation?
I found this plugin https://wordpress.org/plugins/dynamic-qr-code-generator/

Unfortunately this plugin only show the QR code during I edit the listing (at wordpress back end) which does not serve my purpose
