A minor follow-up on identifying credit cards' types

Recently there was a discussion on the list about whether it was
necessary to require users to select what type of credit card they
were entering.

This morning I made a donation through the online service causes.com.
As part of that process I entered a credit card number. There was no
field to select card type. Instead the blank space directly below the
input box for my CC number changed in mid-entry to display the message
"Thank you for using your Visa card." The message was right where my
focus of attention was but didn't seem too intrusive.

I thought this was a moderately elegant solution - it's not perfect in
that it requires running code in the browser (Javascript or AJAX I'd
imagine). I wondered what the experience would be like for blind
users - would they hear that message after they finished typing in
their number and tabbed forward?

I also liked the fact that causes.com embedded my name in the URL I
clicked to get to their page so it was pre-filled in the form for me.
Again, not a perfect solution but it shows that they are at least
thinking about the user experience and working to improve it.

Best,
--Alan

Screen reader users will eventually be able to hear updates like that,
when WIA ARIA is supported, but at the moment it is very patchy. Firefox
3.5 and a public domain reader called NVDA (for Windows) currently
provide the best support for new features like this. Ironically, what
are called 'live regions in ARIA (that can be updated asynchronously)
weren't supported by NVDA when I last tried. They worked in with the
JAWS screen reader, though.

Yeah good solution and I really don't understand why it should be a
problem to validate while typing as some seemed to suggest.

Someone once tried to tell me that requiring the user to select a
credit card type was intended to (or at least served the purpose of) a
protection against card number thieves and such. I didn't quite
believe them then, and even less so now.

However, this still doesn't solve the issue of being able to tell
whether your credit/debit card type is supported, before you start
typing. (Unless they all are anyway, which is very rare.)

I saw a rather neat implementation related to credit card type when I
was buying some tickets recently on Ticket Web. As I was checking
out, I noticed that there was a reference to the security code number
being a four-digit number above the credit card number, and there was
an accompanying image showing where the number was located.

This caught my eye, because my card's security code isn't four
digits, and it's not positioned above the card number. And sure
enough, when I selected my credit card type, the copy and image
changed to reflect the correct information for my card type. It's
just a small detail, but I've observed users having trouble
remembering where to look for their card ID number, especially if
they routinely use more than one type of card, so I thought this was
a nice solution to a fairly common problem.
