A two-dimensional (2D) barcode, also known as a
matrix or QR (quick response) code, is a graphic image that
contains information stored both horizontally (like the
one-dimensional UPC used in supermarkets) and vertically. The added
dimension in a 2D barcode enables the image to represent thousands
of characters-essentially a portable database-compared with only 10
to 20 characters stored in the conventional unidimensional barcode.
Given that added capacity, 2D barcodes are increasingly being used
for fast data access in a variety of settings, and in documents
from drivers' licenses to tax returns.
Perhaps not surprisingly, the real boom in 2D barcode use has
been in mobile marketing. Companies have developed technology that
enables camera phones to scan matrix codes from a website, print
publication, or poster. The consumer can then access content
embedded in the code or be redirected to targeted content via the
phone's Web browser.
The 2D barcodes used in The ASCO Post will connect
readers to further information about the articles they are reading.
For instance, a report from the ASCO Annual Meeting may include a
barcode that will connect readers online to the original abstract
of the study discussed. In this way, the editors of The ASCO
Post hope to provide readers with further resources and
validated information about the news in these pages.
Find examples of 2D barcodes on the pages of The ASCO
Post. Using the ScanLife application (see right), scan these
codes with your camera phone, and see where they bring you. Watch
for more barcodes in future issues of The ASCO Post.
Important: Getting the application
There are 3 ways to download the ScanLife application.
1. Simply text the word "scan" to 43588.
Or
2. Go to www.getscanlife.com on your
phone's Web browser. The application will attempt to determine
which model phone you have. If it's successful, simply select
"Download".
Or
3. Visit the application store for your smartphone (such as the
iTunes Store or the Android Market).
The application is free, though standard data rates for your
phone do apply.
Scanning 2D codes
When you see a code that you would like to scan, start the
ScanLife application. The screen will look similar to camera
mode.
Position your phone so that you can see the barcode and that the
code fills about half of your screen. If one of the soft keys
displays the word "Click," you will need to click that key or the
center key to scan. Otherwise, the code will scan
automatically.
A short audio chime will indicate a successful scan and the
phone will contact the server for further instructions. This may
take up to a minute depending on data speeds and phone type.
