Re: Accessibility of QR code scanning in web pages

Hi Ramakrishnan,

I don’t know of definitive guidance on this, I suspect there are a lot of factors.

For the use-case of "Can someone scan a QR code", there are a lot of steps to achieve that.

For example:
- Can the person use a smartphone? 
- Can the person download a suitable QR scanner, and is it accessible?
- Can the person understand the instructions to combine what the website shows, with what they need to do with the device?
(Not being able to see the screen and point your device at it is an obvious issue.)
- What happens if they are using the device to access the site? How do you scan a code from the device you're using?

Overall, I think the solution will involve providing multiple ways of achieving whatever it is, including non-QR code options.

In the context of 2nd factor auth, you could provide options for:
- Webauth based OS authentication.
- Authy / Google authenticator styles apps providing a time-based-code to type in.
- USB based 2nd factor dongle like YubiKey. 

Relying on one modality or device setup is always going to cause issues for someone, even without adding disability to the scenario.

If you are referring to SQRL authentication, I think that also has a desktop app that can be used without a QR code.

HTH,

    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 Scanning 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?
