The problem
..as I have always seen it with any 'Digital ' or any other official, unequivocal ID is that once it's accepted as the ONLY ID, the opportunity for fraud and mayhem will only be enhanced and increased.
Official ID sir? No further checks necessary.... Was that a new Bank Account you wanted ? An unsecured loan? etc. etc. (it's bad enough now, I know, but at least everything currently should be viewed with suspicion and relevant further checks? Govt. official ID ? pass friend ... no need for any more checks..
No official ID? Your ID 'cloned'/abused by some miscreant ? Data adjusted/stolen/deleted from the database - the one and only database ( I'm sure I'm writing this amongst sysadmins, programmers, etc. )
Have Fujitsu tendered already?)
The FRAUD - you are dealing with miscreants. The MAYHEM will be the bane of the innocent (as always). That's my view of the problem..
