Biometrics Are Coming, Along With Serious Security Concerns

lt will happen globally, it's just a matter of time. I think that they are waiting for the baby boomers to pass away as it would be this generation that would be the most against it. The security concerns are valid. In my line of work, I'm waiting for the day in which they tell me that it's mandatory to comply. They will roll it our to the poorer nations first that are more dependent on government resources and then try to bankrupt the other countries in order to force more reliance and compliance on the state.
