I am looking at developing this system for a touch free experience, but more importantly, know your guests. I have a mix of generations that would either embrace, or call for further assistance. I would hate for a late check-in to be fumbling at the door at night trying to figure out HOW to scan the code. I don't want a 3 star review for my check-in process. Yes, QR codes are "cool" but I haven't seen them embraced in large hotels, so there must be a reason? In fact, there was a great article in FSR magazine about how this might NOT be the way to go.
Hospitality, and certainly AIRBNB is all about providing a fulfilling experience for the guest, not the provider. While I might want to save the planet, the guest might just want the correct code for a door that opens. If great communication was provided beforehand, and my check-in instructions are noted clearly in an organized manner, that's a 5 star experience. A QR code requires that you have your phone with you, and during a relaxing stay, to perhaps check-out for a bit, that's not a good thing either. You're forced to stay tethered to your phone.
A beautifully done, high-quality, well-organized, copied on fine paper guidebook is hands down much better. It creates an experience with the guest, it's personal, and means you care. Isn't that what we're trying to create in our spaces? While I think a strategically placed code might be fun to say' "Hey, we're trying" it's not necessary. Mixing old and new I think is always appreciated. I think we succeed for our guests when WE provide unmatched great service that outshines our competition. Especially in the world we are living in, personal is better.
I would need to place the QR code either at the location of where it would be helpful, or in a logbook of all codes for each appliance. Well, it looks like that would necessitate a "piece of paper", which in fact, could just list the directions. So, my logo and QR code instructions will be on my business card and at my front door. Perhaps just tighten up the availability of the paperless correspondence on the app for ease of use. You can develop your own guidebook online. I will be using our check-in process as a trial run for the QR code.
