QR Codes are used to check and compare product price in-store and online, find books in a nearby library or bookstore, store conference materials, marketing, and so much more.
However, QR codes need a Reader to decipher the code. There are tons to choose from, but a favorite is RedLaser – a free scanning application for iPhone and Android whose functionality goes way beyond simply reading QR codes.
Simply download the app, use your camera to scan codes, and you’re good to go.
- Check product prices – compare prices of products online and in-store and find out which store nearby has your item in stock and for the lowest price. For more information, check out this post we did a while back.
- Find books in a nearby library or bookstore – QR code references to book are popping up all over the place. Scan the code and find out where you can purchase or borrow it. The ultimate library catalog.
- Save information for later purchases – I did this the other day when looking at laptops. Scanned the QR codes of my top two choices on display at an electronics store and emailed it to myself. I could even pull up reviews of the product right there in the store.
