Recently, I’ve been writing a bit about QR Codes (QR Codes and the RAZR V3xx, QR Codes and Twitter and Snappr.net, and QR Codes and political flyers. Now, I’m back from the America’s Future Now conference, and looking at what is going on for InternetWeek in New York City.
This evening, Digg will have a Meetup in New York, and I thought it would be interesting to see if I can use #QRCodes and #digg.
So, I created this QR Code using Kaywa’s QR Code Generator to promote my blog post. Please scan it and digg my post.
Thanks. If you’re going to the Digg Meetup, keep your eyes open for me and say hi.
Recently, I've been writing about QR Codes and I've been thinking about how it could be used nicely. I thought of using QR Codes and Twitter to generate buzz.
(Sends a message to Twitter saying Join me at #AFN http://ourfuture.org/now)
As I went into the next afternoon plenary session, I was handed a sticker that says
Health Care '09
Health Care Can't Wait
text HEALTH to 94553
Now if they added this QR code:
all that people would have to do is scan the QR code with their phone and the phone would automatically send the message.
Now that I’ve gotten my cellphone to successfully process QR Codes, I figured it was time to start exploring a little bit more what I could do with QR Codes. An obvious example is putting your QR Code on the back of your business card. However, if you are going to do that, why not find other interesting places to put QR Codes.
One site focused on making removable bar code tattoos. What I was thinking would be better would be if a person could go to a website, design a QR Code and then have it printed on a shirt, or something like that.
Sure enough, someone else has already thought of that and actually, executed it nicely. Snappr.net allows people to create a wide array of QR codes and buy them on a collection of interesting objects.
They provide three different categories of QR Codes. The first is Classic QR Codes. These include URLs, phone numbers, vCards and plain text. For social network enthusiasts they provide ‘Social Codes’. You select a social network, enter your id on the network, and the provide a QR code for the URL pointing to your id. They also provide a bunch of other specialized codes, but they didn’t do much for me.
When you have your QR Code designed, you can add some text to appear around it or take one of their layouts and then buy a shirt, cap, tote bag, bumper sticker, or other items with the QR Code printed on it.
I created a vCard QR code which I displayed on my computer. When I took scanned it with my cellphone, the phone took me to a webpage of my vCard. It provided an option to download the card, and I downloaded the card into my address book on my cellphone. It worked very nicely.
As I thought more about it, I thought about how QR Codes might be a nice addition to the old Yellow Arrow art project. I also wondered if I could create a QR code to send a message to Twitter.
This code sent the message “Testing QR Codes and Twitter”. Since my phone number is associated with a Twitter account, it came up nicely. Add in some hashtags, and you could have some real fun.
The United State lags in the use of QR Codes, but with a little work, I think we could do some really interesting things with it.
For the longest time, I’ve been trying to successfully install an application on my Motorola Razr V3xx that would allow me to process QR Codes from my camera. This evening, I finally had success. Let me run through the steps that I did in hopes that it will help others.
First, let me start off by explaining QR Codes. QR Codes are two dimensional bar codes that contain information that can be used on cellphones. Typically, it will include a URL, a phone number, text or an SMS message. As an example:
is the QR Code for the URL of this blog.
You can use Kaywa’s QR Code Generator to create different QR Codes. Kawya also has a QR Code Reader. Their reader doesn’t list the Motorola V3xx as a supported phone. However, it does support the Motorola V3x which I hoped would be close enough. However, I could never get that reader to work. It always complained about not being able to access the camera.
i-nigma also has a QR Code generator and QR Code reader. I downloaded their QR Code reader had and the same problem accessing the camera.
This afternoon, I spent a little time looking around and found comments about it perhaps being a Java problem. Various searches led me to the need to replace the j2me_domain_registry.sm with a less restrictive j2me_domain_registry.sm file. A thread on the Midpssh forum pointed me to a zip file of this file:
I downloaded the file and searched around to find the right place to install it. To do this, I used PKCommander. The best site I’ve found about loading and running PKCommander is this: Motorola RAZR V3 - Install P2K Commander - Step-by-Step (Pictures).
With PKCommander installed and your Razr connected to you computer, you want to go to the P2k:/a/mobile/certs/root/x509/kjava/ directory. You should find a file that is around four thousand bytes. Copy this file onto your computer as a backup. Then, copy the j2me_domain_registry.sm I described above from your computer into the directory I described above.
I don’t know if it is necessary to restart the cellphone when you do something like this, but I always like to, just in case. The cellphone started up fine and I went to the i-ningma application. It worked like a champ. I check and this also fixed the Kaywa application as well. I don’t run much for other applications on my cellphone, but I thought I should check a few others as well. One that I run is a free Tetris application which ran fine. The next application I tried was Google Maps.
One of the things that always annoyed about the Google Maps application on the Razr V3xx is that it would always ask for permission to download data from the Internet. I could specify Yes, for this one time, or No. I did not have to option to permanently grant access. The new j2me_domain_registry.sm allowed me to specify Yes, always grant permission, and things work much more nicely for this application and for Gmail.
I haven’t found any applications that don’t work because of the upgrade, but there may be some.
So, now I’m running with a slightly more modified Razr which is working nicely and allowing me to access QR Codes. Perhaps I will try some other applications soon as well.
