Why is detecting credit cards even useful?

I know what card I have, you telling me "Yep that's a VISA card" isn't really that helpful. Yes, I might enter the first four digits wrong and see the wrong card icon light up may help me a little, but aren't I just as likely to enter the last 12 digits wrong. In the case of VISA you're pretty much just telling me "Yep, that first one is a 4".
