QR codes are everywhere. If you haven’t noticed them on signs, direct mail pieces or store windows, you’re just not paying attention. QR codes (Quick Response codes) are a way for your prospects to interact with your marketing, and your business should consider getting on board.

Every business has the potential to use QR codes in an unexpected way. If your business innovates its marketing campaign with QR codes, you're bound to enjoy a healthy ROI in addition to increased customer interaction. Keep reading for our list of six interesting places we’ve found QR codes.

Menus
Print a QR code on your menus to engage restaurant diners. The QR code could direct them to a video of the chef preparing an entrée or even nutritional information. Somewhat obvious caveat—if the food’s fatty enough to make guests lose their appetite, stick with a server bio or something else to spark a diner’s interest.

Invitations
Event invitations with QR codes can link to a landing page where invitees can RSVP or check out directions to the venue.

Real Estate Lawn Signs
Realtors are attracting passersby by printing QR codes on their listings’ lawn signs. The link leads potential buyers to sites with video walkthroughs of the house and all the details included in a sell sheet. QR codes help realtors hook prospects before they walk past the home and forget about it. Sold!

Receipts
Most consumers research a business online before patronizing it. Make sure your online presence is strong and then print QR codes on your business’s receipts. Link to a landing page inviting them to comment on your stellar service and enjoy a boost in your number of online reviews.

Coffee Bags
Starbucks recently rolled out a QR code campaign that takes an educational approach to the QR code trend by linking to videos of coffee experts or music samples from the region where the coffee beans are picked. Faithful sippers now have even more reason to congratulate themselves on drinking coffee.

The Back of Your Head
We don’t really expect that you’ll have a QR code shaved into your head, but it’s been done before and it gained a lot of attention. The entire starting lineup of the UK’s Bromley football club had shockingly realistic QR codes shaved into their heads for a recent match. No word on whether any fans actually tried to scan them.
