The whole time I was reading this all I could think was "man, this reads like a bad advertisement."

Then I noticed the disclaimer (horribly placed; I skipped over it the first time because it looked like a caption text for the banner image): Editor’s note: Simon Black is CEO at London-based Sage Pay.

edit: So, this is a long-form advertisement for a payment processing company. Why do people still read tech crunch?

Also, biometrics for payment? Christ, because payment processing hardware/support/service isn't expensive enough already! And has the past decade of massive privacy violations by both the private and public sectors taught us nothing?
