QR Code Woocommerce

Firstly, this plugin is awesome!

I am using this plugin in my company as part of our stock management system. The QR plugin allows for simple and variant products to each produce their own unique QR codes, which can then be generated into PDF format and printed.

If you're like me and use label printers, the PDF's that are generated are perfect as they can be sent straight to the label printer and automatically resize themselves ready for print. I then use these labels out in our warehouse to inform colleagues of what stock we have out there, and they can use their mobile phones to scan the QR codes to find any additional details without needing to come back into the offices.

The developer (Gangesh Matta) is a good person. He has worked with me to implement some great changes along the way and the changes have all been carried out very quickly, very professionally and he has always been able to build or develop whatever has been requested. He is unlike a lot of the other plugin developers on this platform and you can tell he cares about his plugin and the people that use it and I have a huge amount of respect for that.

I look forward to seeing what changes this plugin goes through in the future and know that Gangesh is currently working on a number of changes that will add even more functionality to this already amazing plugin.

I really can't thank you enough.

And if you're wondering whether to get this plugin as a solution to you barcodes/QR code requirements, then I cannot stress enough - Download and use this plugin! You will not be disappointed!

Amazing Plugin and even more amazing Developer!
