I am not sure you understand what you are talking about. Have you ever been to Africa? Asia? South America? Or any place where some of the 2 billion people live on less than $2.50 cents a day and scrape to live in the depths of poverty and struggle? Or been somewhere where some of the 2 billion people without bank accounts can't participate in the economy?
Or met any of the 1 billion people who are illiterate and would not have a clue how to interpret text on a paper never mind on a phone?
Your concern about biometrics is what I call a 'White Man' problem that is born from a life of privilege in the West. I suspect you are cryptoanarchist or a hard core Libertarian and that's fine. Or maybe even a Bitcoin Maximalist.... But honestly, your concerns are far different than the people who Humaniq is aiming to lift out of poverty and improve their lives.
In fact it IS NECESSARY to take their biometric data. Because that allows them, even when they are illiterate - to protect and safeguard their data on their phone. It gives them an identity which they can use to access more than just banking services, much like a profile on Facebook but is rock solid and gauranteed to be theirs. One that can't be hijacked or stolen, or ripped from a database. It's them and it's theirs. Protected and safeguarded in a Blockchain.
Do YOU understand what I am talking about?
