It looks like mobile 2D barcodes are starting to catch on in Europe at least. When I was in Japan a couple of years ago they were everywhere, on handbills, maps, business cards, product packaging and in magazines. The idea is that you point a camera phone at a barcode and take a picture. Software in the phone decodes the image and takes you to a mobile website, downloads a ringtone or adds contact information to your phone’s address book. Almost all Japanese phones come with code readers.<\/p>\n
The rest of the world is starting to adopt this technology. Nokia is bundling a barcode reader with the E90, N93, N93i and N95 (including the US market N95-3). With millions of these phones in circulation we are finally at the point where if you put a barcode on something, there’s actually a good chance that someone will spot it AND have a phone with a barcode reader. Marketers seem to be taking notice too, lately QR codes have appeared on British movie<\/a> and TV series<\/a> posters, car ads<\/a> in Germany and in a South African newspaper<\/a>. The BBC<\/a> is using them on promotional materials and Google<\/a> is putting them in print ads!<\/p>\n
I think one of the best uses for barcodes is mobile website discovery<\/strong>. At WapReview.com<\/a>, I’ve created a directory of over 1000 mobile sites which you can search and browse to find sites with a particular type of content or ones that just look interesting. That’s good but how do you get those sites on your phone? You could just type in the URL but that’s a hassle on a phone keypad. Or you could point your phone’s browser at yeswap.com<\/a>, a mobile portal that mirrors the directory structure of WapReview.com and is searchable. But now there’s an easier way, every site on WapReview.com has a QR Code included as part of its listing. Here’s an example:<\/p>\n
It started when I found this great open source library for creating QR Codes, the same code format used in Japan and the most widely used type of mobile 2D codes in the world. The library is by Y. Swetake<\/a> and it’s pure PHP so it even works on my shared hosting where I can’t install binaries.<\/p>\n
Nokia offers a reader download<\/a> for the N80.<\/p>\n
For other phones, go to Semapedia.org<\/a>, who’s goal is to tag real world places with a 2D codes that point to a Wikipedia article about that place. Semapedia’s homepage has a web form to help you find a reader compatible with your phone. If your phone is not listed on Semapedia here are several QR Code readers you can try:<\/p>\n
There are a couple of Java ME<\/strong> readers from i-nigma<\/a> and Kaywa<\/a>.
\nIf you want to create your own QR Codes<\/strong> you don’t need to install Mr. Swetake ‘s code on a web server, there are a number of QR encoders on the web. Nokia has one<\/a> as does Mowser<\/a>.<\/p>\n
I can’t mention 2D codes with putting in a plug for Scott Shaffer’s blog, The Pondering Primate<\/a> which is all about what Scott calls, “Real World Hyperlinks<\/strong>” which includes both barcodes and NFC tags. Kaywa’s blog, All About Mobile Life<\/a>, is another good starting point for anyone interested to learning about 2D technology and the growing business opportunities around it.<\/p>\n
Update<\/strong>: I got an email from Roger mentioning his blog, 2d code<\/a>. I just took a look and agree 2d code<\/em><\/strong> is well worth visiting, in fact right on the front page I learned about two more QR Code readers. ZXING<\/a> is an open source effort supporting J2ME (although it didn’t work on the two Java phones I tried, a Samsung A920 anda Motorola i855) , J2SE, and Android<\/strong>! The other is iMatrix<\/a> a native app for hacked iPhones<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
