QR Codes are images are intended to be scanned by a smart phone camera, which hold graphically encoded information.
It can only hold a single type of data so it’s often used to hold URL’s which then send people somewhere that they can get more information on something.
This is a great tool for marketters trying to link offline campaigns such as flyers, posters, etc. with online efforts and information.
There are a lot of high quality free tools to make QR codes so it’s not worth purchasing software to do the job.
To make QR codes yourself try visiting these free options:

When you insert the QR code into artwork try to keep it at least 1″ square with a few mm’s of white border. They are and can be made as large as you think a phone could scan. If you do plan on resizing the image to make it larger I would recommend a vector image (normally in pdf format) since it resizes without loosing resolution.
Hope this helps and if it did please share
