Subject: Accessibility of QR code Scanning in web pages
No previous message | Next message →

Dear members,
I would like to know your thoughts on accessibility of QR code
scanning used in web pages for different modality. These days we have
been seeing QR code Scan being used in web sites for Multi-factor
authentication (MFA) and some other scenarios. I would like to know
your thoughts on the Accessibility of QR code Scanning in web pages
for different modality.
Is it considered accessible? Or, is there any accessibility challenges
for users with different modality?
Is there any guidance available for evaluating accessibility of QR
code Scanning in web pages?

Thanks
Ram

Hello Ramakrishnan,
As a blind user and accessibility specialist, I can tell you about the
great challenge for blind and low vision users: positioning of the
smartphone in front of the screen of the PC.
As an example, let's take WhatsApp and their Windows client. It is
basically their website wrapped into a binary file, and to
authorize on your PC, you have to place your phone in front of your screen to scan the QR
code. And it's really a pain, because even a sighted person is helping
you with the thing, it's like: "lower... a bit higher... a bit to the right... no no
no, lower and a bit to the left!" - I hope, you got it.
So if you design an app that requires a user to scan a QR code from
his/her cell phone, I guess you need to also design some kind of a
mobile app that would guide the user about where the QR code is, if
it's possible for you.
Hope this helps.

That just sounds like a bad QR code reading program. We are currently doing functionality testing on an application that has a QR code reader and I am always astounded how fast it reads the codes. You don't need to keep the phone still even for a fraction of a second. As soon as the QR code is in view of the camera it gets read instantly - even before my eyes have registered that it's fully within the viewfinder. The QR code only needs to occupy a few percent of the viewfinder, so you can just wave the camera in the general direction of the QR code and there is no need to worry about centring it. It also works at an oblique angle so there is no need for the camera to be parallel with the QR code.

In some (or actually most) of the merchant places here in India, we use
Paytm interestingly, as the app triggers the QR code, it sounds a beep. So
that alerts us if we have scanned QR code.

I think something like that should be implemented.

Hello,
I find QR codes extremely annoying, so that is one reason why I don't use
Whatsapp.
They are accessible if I can trust when I point my phone to the screen, I
get the QR code.
I have had dialogues warning me of updates block the QR code though and I
had no idea. Apparently some brilliant person thought it would be a good
idea to make dialogues that are always visible, but don't trap focus as
well, so I could have a dialogue telling me something that is blocking my
screen, but I would have no idea.
Other times QR codes would be a problem is when accessing the site on a
device without a screen. Most Braille notetakers don't have a screen.
Also accessing the site on a mobile device is a problem, because I don't
know how to point my phone's camera at it's own screen.
If users don't have their phone, or their phone is dead, or they don't have
Wi-Fi with their phone, they couldn't use the site.
If there is an alternative that doesn't require the phone along with the QR
code, I think you'll be fine.
Thanks,

From a meta view, for me the question seems rather easily to answer, similar
to a lot of partially inaccessible features:

1. If the feature is helpful for some, it's allowed, perhaps even indicated.
Just compare the effort to access via keyboard input with a smart phone
interaction for those, who are fit for smart phone interaction.
2. Guarant an alternative access for those, who don't have the corresponding
device or app available. I qutoe Brandon: "If there is an alternative that
doesn't require the phone along with the QR code, I think you'll be fine."

Besides accessibility questions I'd be longing to know, how secure QR is for
two way authentication. I could imagine hacks to pretend a human being when
accessing a QR code. This could be a query to technicians in conception
times.

Hello Steve,
Sorry, but if you're blind, it doesn't help. The main thing is to know
where in the world, I mean, on the screen, the QR code is, and
position the cell phone accordingly, without even speaking about
angles and such things :(.

I'm not disputing that it may be difficult. I was just pointing out that the original poster seemed to be using a particularly bad QR code recognition application. A good application like the one we have been testing, can be very tolerant of position and angles. We just need to wave the phone in the general direction of a QR code and it gets read accurately.

The only problem we have is if there are two QR codes close to each other. That can plausibly happen with our system, which uses both printed and on-screen QR codes, but there will be plenty of cases when it is unlikely.

Hello Steve,
Sorry, but if you're blind, it doesn't help. The main thing is to know where in the world, I mean, on the screen, the QR code is, and position the cell phone accordingly, without even speaking about angles and such things :(.

That just sounds like a bad QR code reading program. We are currently doing functionality testing on an application that has a QR code reader and I am always astounded how fast it reads the codes. You don't need to keep the phone still even for a fraction of a second. As soon as the QR code is in view of the camera it gets read instantly - even before my eyes have registered that it's fully within the viewfinder. The QR code only needs to occupy a few percent of the viewfinder, so you can just wave the camera in the general direction of the QR code and there is no need to worry about centring it. It also works at an oblique angle so there is no need for the camera to be parallel with the QR code.

A similar experience with people who have mobility or dexterity problems.
Holding a device at the right position for a few seconds feels like an eternity.

Thinking of finding QR codes on a PC screen, there is an App called Voiceye Phonemarking that will locate them with bleeps that change to another sound when you have successfully captured the link to the website or content. It is not new and is available free on Google Play https://play.google.com/store/apps/details?id=com.voiceye.reader&hl=en_GB or as an iPhone app https://itunes.apple.com/gb/app/phonemarking/id407918832
