Also, why can't sites display your card number in groups of four digits just like they're shown on your card. This makes it much easier to verify your card number for people with poor eye sight. Some sites do, most don't.

Visa/MC numbers are 4x4, as you are describing but AMEX is 15 digits and Diners Club and Carte Blanche are 14 digits. So you need to pick your poison: Either ask people what kind of card it is and then group their numbers nicely ... or don't ask them what kind of card it is (since you can tell anyway by the numbers and schema) and have ungrouped numbers. I prefer the latter, actually, since it annoys me to be asked a question that the site can infer the answer to ...

  CC inputs know within 2 or 3 digits... it's how some entry forms display an Amex, MC, Visa icon in the input window.

  You can pretty much infer the type of card as they enter it, the with first 2 digits signaling the card and this format in 90% of use cases worldwide.

    enough letter spacing is enough for users with poor eyesight

      I have a good eyesight and still select 8 middle digits to make a verification contrast. Grouping is about memory, not eyesight.

      I’m having trouble figuring out what this was aimed at. My comment was aimed more towards what the website can do and how it formats numbers when a user enters them. Building in accessibility is a net win to all users, even those who think they may not directly benefit, spacing things out in a reasonable and predictable way helps everyone and especially those with eyesight, memory, and attention issues.

  I dont think I've ever seen a Diners Club/Carte Blanche in my lifetime, with a DC/CB number, most of those are issued as Discover or Master Card now.

Or at least allow you to put the spaces in yourself and then just strip them out.
