There might be some distopian way of doing this using biometrics and cryptocurrency. Submit your "human hash" (e.g. some set of cheaply collectable and individually unique biometric signatures) and receive one USDT or similar fixed value digital currency. Then just slowly allow people to register ownership of their dollar as/when they decide to collect it. This only gets to people who can get access to a computer and the crypto-dollar is functionally useless to most of them but it's pretty cheap to distribute. The biometrics bit may also be literally impossible - no idea what the state of the art there is like.
