This post is in follow-up
to an earlier post titled "RIP: Why We Don't Need QR Code Campaigns." Several
critical points made by commenters merit further examination. These are:
Many URLs are too long to be easily input, even
with a QWERTY keypad.
In the end this will go
down to individual comfort levels, but there is some powerful anecdotal
evidence to the contrary. If we consider SMS messages, the average length of
which is approximately 25 characters, combined with the fact that the average
American sends over 300 every month. It follows that Americans are quite
comfortable typing on their phones, QWERTY or otherwise, and that in the US thumbs
are tapping out well over 7k characters each month.
Based on SMS volume, it
stands to reason that if marketers can get their URLs down to 25 or fewer
characters, US audiences will not balk at being asked to type it into their
browser. To help with this, there are services like Budurl that enable branded
URL shortening.
There are more mobile phones with cameras than
there are devices with QWERTY keypads.
Yes it's true that
mobile phones with QWERTY keypads account for a minority share (18-25% depending
on where you look) of the US market, but it's also true that that minority accounts
for over 75% of all mobile web traffic. The truth is that the majority of
users aren't likely to use their phone for much more than making calls and
sending SMS messages. On top of that, many of the feature phones used by the
majority, that don't have QWERTY keypads, also do not have cameras with high
enough resolution sensors to be capable of decoding a 2D barcode.
Use of 2D Barcodes allows the passing and/or
capture of channel, tracking, location and personal data that URLs do not.
Yes and no. In theory,
with a specialized reader, a redirect from a barcode scan could pass data about
me, and where I'm coming from - name, location, phone number, basically
anything stored on my phone - into a form on a mobile optimized site. However, doing
this would require a specialized reader and form. There aren't any open
standards that are used widely enough to make this more than proprietary
functionality. So, the tradeoff really becomes untenable for marketers when we
consider drop-off associated with requiring audiences to download and install a
proprietary application.
It's also worth noting
that much of the aforementioned data can be captured with a shortened URL
redirecting to a mobile site. Several mobile browsers already allow location
data to be passed to a mobile optimized website.
Generally, 2D barcodes make for a better user
experience than URLs.
The process of decoding
a barcode is not as straightforward or error free as many of the technology's
proponents seem to believe. Current reader software/hardware combinations
suffer tremendously high failure rates. This is especially true of software/hardware
combinations that require users to take a picture and then decode it, as
opposed to decoding through an active camera.
Moreover, putting the
onus of driving reader software adoption and educating a target audience on a
brand detracts from the delivery of primary campaign messaging. Between
education, download, and install the use of 2D barcodes in place of URLs adds
too many friction points to be worthwhile. Marketers should be doing everything possible to get their
message across. Using a barcode instead of a URL distracts from clear
expression of that message.
QR codes and 2D barcodes have other uses beyond
directing users to a URL.
This point was conceded
in the initial post: "there are other uses for 2D barcodes that make sense."
Clearly 2D barcodes can be useful, but integration with mobile platforms for
specific utilitarian purposes will likely require specialized reader software
for each unique purpose. The critical point to recognize here is that the
use-case that popularized the technology in Japan, easy input of URLs, does not
translate to the North American market. In NA, the trend toward QWERTY keypads
eliminates the need to use 2D barcodes as a URL input mechanism. Smartphones are
not widely used in Japan.
It is too early to
proclaim the death of 2D barcodes for any and all mobile uses, but expect to
see image recognition and NFC give barcodes a run for their money. That said,
it is worth considering interesting ways to use QR and other 2D barcodes with
mobile phones, that can't easily be
replicated with a URL and mobile-optimized site?
2D barcodes can contain
as many as 4,000 alphanumeric characters depending on size and type. Using
barcodes to transmit data in spaces that lack network connectivity could
provide significant value for both marketers and consumers. For instance, print
ads in subways might use barcodes to allow people to save or receive additional
information about a product or service directly to their phone.
Barcodes have been
widely used in inventory management infrastructures since they were first
introduced. Starbucks' use of QR codes in their gift
card iPhone app is more an extension of infrastructure capability than a
marketing play. Although it does have important implications for its marketing
and advertising.
