They're being intentionally vague. Their argument is that they're only mapping from palm to credit card number and mobile phone number, which isn't the same thing as mapping from palm to real identity name (unless you also link to your Amazon account). Which belies the fact that it's much easier to map from a credit card number or mobile phone number to a real identity name.
