What‘s the Power behind 2D Barcodes? Are they the Foundation of the Revival of Print Media? Paul Schmidmayr Martin Ebner Frank Kappe Social Learning / Computer and Information Services Institute for Information Systems and Computer Media

Introduction
Combination of 2 technologies:
2D Barcodes
Camera-equipped mobile phones
Link from the real world to the digital one

Overview
Types of 2D Barcodes
Mobile tags and camera equipped mobile phones
Applications of barcodes related to print media
Issues to be solved
Conclusion

2D-Barcodes für Mobile Tagging

QR-Code (QR)
„ Quick Response“ Code
develped by Denso-Wave Corp., Japan 1994
patent not exercised
originally for logistics applications
agreement between mobile network operator and mobile device manufacturer 2002 to use QR-Codes. Within 9 months barcode-readers (from 3G Vision) pre-installed on most of the new mobile devices. Meanwhile on approx. 75% of all jap. mobile phones
allows the coding of kanji-characters

Data Matrix (DM)
1988 developed by NASA, DoD and other companies
like QR-Code also ISO-standard
Requires approx. 37% less area than QR-Code for the same data

Beetagg (BT)
Swiss company ConnVision
Codes optimized for european devices (no autofocus and macrolens)
Support for several OS (Symbian, Windows Mobile, Palm, Java)
Branding (with QR-Code and Data Matrix also possible)
Proprietary (advantages vs. disadvantages)
Cooperations with several companies

ShotCode
Most seen in america
Big campaigns in Mexiko with Coca Cola
Diameter of code is usually: 3,5 cm

Capacity of data storage (1/2)
How many characters can be encoded?
Number of characters determines the size of the code (QR, DM). The question has to be: „which size of code can still be read with mobile devices?“
Recommendation: usage of service to shorten the URL to 16 characters max.

Capacity of data storage (2/2)
Encoding of data types (e.g. images)?
determined by the size of the code
Images are possible: the data can be split to several QR-Codes
Ringtones

Conclusion 2D Barcodes
QR-Code and Data Matrix ISO-standard
Open mobile alliance, GSM association, GS1 agreed last July to use both as a standard
interoperability reasons ask for standarized data format

Mobile tags and mobile phones
Placing the 2D Barcodes in the real world: „mobile tagging“
Barcode reader at the moment only pre-installed on high end devices
Reader for most java-enabled mobile phones available to download
Connetion to internet

How does it work?
1) starting barcode reader on mobile phone
2) directing the camera over the barcode
3) application decodes automatically
4) save data, follow link,...

Barcode-Reader
I-Nigma, Kaywa, Neoreader
Zxing Projekt von Google (Java-Library)
readers are free
for some codes generation and administration e.g.: BeeTagg, ShotCode with costs

applications (1/2)
business card (vCard)
calendar entry (iCalendar)
simple text
phone number
preformated SMS or email (subscription,...)
RssFeed
data exchange from the display of a second device
tattoo
print on clothes (T-Shirt, bags,...)

applications (2/2)
URL (mp3, video,...)
coupons (McDonalds)
print(newspaper, magazine, flyer,...)
blackboard
flatscreen
mobile payment (H&M, Scanbuy)
videos: Pet Shop Boys

applications print media
Welt Kompakt (Nov 2007): german newspaper: link from print to online content
Spektacle (Nov 2007): bi-monthly magazine for design, fashion and music (London); online update weekly basis
Google Print Ads (Nov 2007): barcodes as additional offer

Advantages for publisher
measurement: when people are reading which content in the newspaper.
topics with greatest interest
new revenue stream for newspapers: affiliate link
polls
comments on articles
whole interview as mp3-download
prize games

Advantage for reader/user
A short URL like tinyurl.com/6r2xhs needs about 41 keystrokes on a mobile device – and this is a short URL
The data entry is a barrier on mobile devices: also with the best content delievered
One pillar of Web 2.0 is the participation – 2D-Barcodes with mobile phones provide a simple and easy way for readers to participate on the content of the paper undependent of their location

Conclusion
2D-Barcodes together with a camera-equipped mobile phone provide a simple method to improve the data input to the mobile device
Since the agreement of OMA, GSMA for standardization the widespread usage can be expected in the near future
Offers several advantages to enrich the print media with a different experience
