One of Microsoft’s announcements on CES09 was Microsoft Tag. Do you remember last try of Microsoft to create mobile barcodes on Live platform? I remember it. So why Windows Live Barcode was deprecated, while Microsoft creates new one? What the key difference between Quick Response approach, barely adopted by industry and new colorful MS stuff? Let’s try to understand differences and approximate future fail or success on this technology.

QR vs. Microsoft tag

Key differences:

  • The only information contains inside MS Tag is ID, which should be used to fetch all relevant information from tag server while QR contains all necessary information and can be used offline. Both technologies have it own advantages and disadvantages. From one hand, you can manage and fix results all the time, from the other hand, what happen with fraud and offline usage?
  • MS Tag using High Capacity Color Barcode (HCCB) technology, which makes able to encode more information into relatively small area. Also because of small amount of information, errors can be handled easily for MS Tag. For encode 1 byte we need 8 symbols in QR codes, while in MS Tag only 4.
  • MS Tag using thee base colors (CMYK) while QR only two (BW), thus in offset print MS Tag is much more sensitive to the quality of color plates. From other hand, if I my approximation is right, MS Tag can be printed in gray palette too, due to the fact, that it uses color differences, rather then color codes for decoding. Also it seemed, that hardware used for four barcodes will be more expensive, than similar hardware for two colors.
  • Because of the fact, that QR is mature technology (first ISS was presented in October 1997), there are huge amount of devices, supports it natively, while MS Tag is rather new. From other hand, http://gettag.mobi/ provides WM,J2ME, IPhone, Blackberry and Symbian native clients for reading MS Tags. So it seemed, that very soon (if Microsoft will not abandon it again) this will be distributed de-facto.
  • QR Code® is registered trademark of Denso Wave Inc, which makes this technology problematic for future enhancements, also HCCB, used for MS Tag is licensed by Microsoft, however as far as I understand from their IPL site, it can be used as far as remains under MS patent agreement. But maybe an appliance of this technology is protected.

Bottom line – I’m very skeptic with MS Tags, however let’s give it a chance and see whether MS Tag will become another Semacode, ShotCode, PDF417, Dot Code, Aztec Code, etc. or become Barcode technology we see every day everywhere…

Meanwhile, you can create your own MS Tag, download free reader for your mobile device from http://gettag.mobi and decide whether you like it or not. For me, this technology is cool, but the code itself is very ugly :)

Be good people and have a nice day.

I currently managing to finish my programming to make a barcode generator by myself. That's terrible, I shall proceed with caution. And I just brought an barcode generator component so as to make a barcode generator by myself. <a href=” http://www.onbarcode.com/products/iphone_barcode/barcodes/qrcode.html”>QR Barcode Maybe you can have a try and have a discussion with me.

Good presentation about barcode types, especially QR Code . Maybe ,you can manage to finish my programming to make a QR barcode generator by yourself.

Thanks for sharing the useful little idea. I’ve know about the QR code generator for a long time and even have managed to generates them based on the URL of KEEPAUTOMATION Free Online Code Readerand it is really convenient and useful. Hope it will be helpful. Maybe you can have a try and have a discussion with me. Thanks and Regards
