I like the idea about putting the bar code on your card, but i would have to disagree about creating simple cards versus flashy ones.
I think it is important to make your marketing materials stand out and your business card is about as crucial a marketing piece as they come so i think that creating a strong visual image with your card is important to getting people to call you, because i don't really care if someone puts my info in the computer if they call me and the job of my card is to generate that contact.
Anyway, you make some valid points but i think ultimately a well designed card is going to catch more peoples attention then a card thats easy to scan. Just my 2 cents.
