The Mobile Future--QR or NFC?

One of my students recently attended the mobile unconference in Boston and sent back dispatches from the field—thanks, Mike! One talked about QR codes and NFC tags. I wasn’t sure what the difference what the difference was, so I thought I should find out.

I’ve seen QR codes around for awhile. This is a shot from a Google Places page I maintain that invites me to “Share Your Place Page with Customers.” When you print out the QR code poster, this is what you get—a simple poster to place in the window. When a mobile phone with the appropriate reader (free here and, of course, on the iTunes store) is trained on the code, it links to the Place Page and the business information it contains. The QR code is a bar code that is read by the mobile reader--technology we’re all familiar with.

Ok, that’s great—so what is a NFC tag. NFC stands for near field communications; cutting through the techno-speak that means wireless connectivity. It’s hard to find a non-technical definition of NFC tags. I’ll settle from for this phrase from the NFC forum: “short-range wireless interaction in consumer electronics, mobile devices and PCs.” That phrase on their home page links to a nice non-technical explanation. The graphic shows what the two types of tags look like, but it’s not helpful in understanding the differences. It comes from a video on this site which has nice music but no narration!

This video is useful; it uses a scenario to explain what NFC tags can do. It comes from the University of Munich (in 2005!). Sincere thanks to the professors there for posting it in layman’s English! You really need to take the 5 minutes to watch the video and understand the potential power of this technology!

Everything I read while researching this admits that NFC codes are way cooler and have the potential to do more than QR codes. QR codes are, however, easy to create and for the consumer to use as my Google Places example shows. NFC codes require devices (likely mobile phones) to have built in NFC chips. Not many have it at present, especially in the US. The ones that do appear to be pricey. For now it appears that we’ll need to keep an eye on the NFC trials taking place in Europe, so we need to once again thank our colleagues there for leading the way into the mobile future!

I think the QR code has a very important and relevant advantage over the NFC system due the cost. Meanwhile the QR code is free to generate and almost all smart phones have already their app, the NFC implies the investment on a chip, which is not that cheap.

I am overwhelmed with several uses of the QR codes. Here in Colombia there is a big opportunity due to the fact that few people or companies know the scope of this tool.

I believe the companies’ which can manage this kind of technology mixed with the social media, will have an interesting advantage.
But we have to be aware that NFC technology is going to more popular and so economically accessible.

It is amazing how fast are going the apps which can be used to improve business. For instance Shazam is an interesting app where you can tag to the mobile the song it’s out there. If you go to a Starbucks Coffee and you heard a song you like, you just run the app and it will show the song you are listening. Then you can decide if you want to hear it or buy it.
Another interesting app is With this app you can share information to one phone to another just by rubbing your finger from one phone to another. If you prefer sharing information by simulating playing tennis you can do it.
