When I look at my Visa, I see a lot of wasted space. It seems that all the stuff on them could be compressed into something half the size. the numbers, expiry, name etc; the logo; even the chip, and magnetic strip could all go on one half alone. Or is the strip a physical limit because it needs to be long enough to swipe? Perhaps the current size is considered by some to be optimal. But to me it seems antiquated and unnecessarily big. Maybe I care too much!
