More likely scenario in the next 10 years would be making purchases with your phone by entering a password or pin on the screen of your phone to confirm. The Biometric portion is a little bit sensationalist at this point because the less invasive Biometric techniques are not accurate enough to verify with 100% accuracy that you have your phone in your pocket. If I have to take a photo of my eye to complete the purchase using my phone, I think I'd rather enter a password. I think the easiest way around the biometric thing is to put an NFC chip under the skin to handle a public/private key exchange. This is the best way to verify your identity because even a DNA test would not prove that you are present in any way.
