…What doesn’t exist yet is a Google-approved or Google-designed system that ties it all together — NFC, payment and biometric ID. But with Apple apparently taking the lead when it comes to using a cell phone as a debit card and a universal ID, you can be sure Google will step up and do whatever is necessary to compete.
I believe that it will soon be possible to live without passwords or credit cards. If Apple builds in these capabilities, you can be sure Google will. And if Apple and Google do it, so will all of their competitors.
It won’t be easy — we can look forward to messy standards and privacy battles. But once they ship cell phones that can replace both passwords and credit cards, I think life will be more convenient — and more secure.
