o2o ‑ QR Codes Unlimited

This app is fantastic! You can create QR codes in batches, filtered by product type, collections, etc., which is a huge timesaver. The batch result is easily downloadable as a zip file. QR codes are also customizable -- add text, change the shape/frame of the QR code; etc. Really a great app that I recommend to anyone needing to generate QR codes for every product, collection, order, etc.
