Here in Venezuela there has been a biometric payment system (fingerprint) for a few years now. Called "Biopago", this system belongs to the main state bank (Banco de Venezuela) and has the widest population coverage. This system allows to make a payment by placing the fingerprint and get paid not only from the bank of origin of the device. But from any bank in the country's banking system, whether state or private.

It has increased its reach lately and may have a greater use. Because the device is seen in many more commercial premises. And for many it seems "more comfortable and easier" to make the payment this way.

Only now the biggest bank, the State, has more data on the consumption of the users and you know what an authoritarian government like the Venezuelan one will want to do.
