Amazon Wants You to Pay with Your Palm

About security and privacy:

> Amazon says this is secure in two ways. First, the company transmits only an encoded abstraction of your hand scan, in a proprietary format, which can’t be used to reproduce an image of your hand that could be stolen, even if attackers could get at it. Second, the company says it protects this data with the same systems that protect user data and credit-card information on Amazon.com itself.
