In few years, we expect the basic infrastrcuture in place. Infrastructure includes no-frills bank account when Ram got his UID number. We also expect banking system to incrporate UID number in their system and complete interbank transfer using UID #.As his attendance data is processed, throug NREGA scheme, weekly payment will be directly deposited through interbank system to his bank account. If there is a mobile phone number tied to his UID #, he will be notified of the deposit.More importantly, usign his biometric, he can withdraw money through local bank representatives in the village.Entire process will be near instantenous and without any intermediate agents.
