This is unacceptable. Not only because the Fed should have nothing to do with this. And not only because the gov really shouldn't need to track which people are participating or even possibly what they are eating. But because the gov should not have fingerprint registration data (which will be horribly abused) .
Stand up for your rights, people... and the rights of your children. Once you give this data to the government (or big business), it will NEVER be erased or restricted, regardless of claims or laws- it will go into huge databases and shared between all agencies and used however they want for as long as they want.
There is only one safer and practical biometric I know of- that is deep vein palm scan. That registration data cannot be readily abused. It can't be latently collected like DNA, fingerprints, and face recognition can. You have to know you are registering/enrolling when it happens. You don't leave evidence of it all over the place. When you go to use it, you know you are using it every time. And on top of all that, it is accurate, fast, reliable, unchanging, live-sensing, and cheap. If you must participate in a biometric, this is the one you should insist on using.
But we also need to realize that IT IS NOT EVERYONE'S BUSINESS WHAT WE ALL DO. The first step in securing freedom is privacy. When you are tracked, you are losing your freedom, whether you realize it or not.
