Btw, your fingerprints are in the database, as some facial features too. That could be in addition to retinal scans and, why not, DNA features too in the future.

Thanks to all those biometric data, in case of a problem, the process will be much more reliable using the database than using old fashioned paper IDs.

Also, all these tests are very fast to perform (excepted maybe DNA tests), much quicker than the unreliable administrative cross-checks that were performed until now when there was an ID issue.
