When , I had just made my first custom QR code, so the idea was pretty exciting to me and I really wanted to have one of these unusual key ring attachments. But later that day, I noticed that two of my three roommates don't have a smartphones. I couldn't help but wonder how many of the people who found my keys would have smartphones, and how many of them would even know what to do with a QR code.
Now, I probably could have done research with statistics and percentages of smartphone users and QR codes and so on, but that sounded boring, so I decided to put this idea to the test.
I went to a local hardware store and had them make some copies of an old key. Then, I printed out a page with the QR code tiled across it and took that sheet to FedEx to get it laminated. I cut out the QR codes into tags, and attached them to 6 key rings with the old keys on them. When someone scanned the QR code, it would compose a new text message that they could send to me to let me know that they found the keys.
I left the keys throughout San Francisco, dropping one at a bus stop, two in Golden Gate Park, one in a parking lot, one in the parking garage at San Francisco State University, and another on a random street in the .
A few hours after I dropped the keys in Golden Gate Park, I got a text with the message, "I found your keys!". Needless to say, I was quite excited. I had a brief dialogue with the person who found the keys and they agreed to leave them for me at the in the park, where I easily found them later. So far, success!
The next day, I got a text about the other key I left in the park. The finder said they had left them by a bathroom, and after some picture messaging, I managed to find the correct bathroom. However, after searching for an hour and texting back and forth with the finder (who was super helpful, by the way), I concluded that somebody else must have taken the key for whatever reason.
As for the key at the bus stop, it took a few days, but I eventually got a text saying that it was still there waiting for me. But when I got there, I found a mangled keychain with the QR code peeled open and the key gone.
As for the others, the QR code could have gotten wrecked or the keys kicked into a bush or down a drain. Here are some tips for those of you who want to make your own:
The verdict? It's an awesome idea and I suggest doing it, but definitely add your phone number to the back for non-smartphone users.
