You can have a discussion about how to implement voter ID without deciding whether it's a good idea overall, or whether it violates the VRA.

In fact, most voting machines don't check ID at all; they leave that to the humans. (If they did check ID, the machines could secretly match votes to names.)

Whether or not they have it now is irrelevant (it's an example) - any proposed technology would inevitably see this requirement, and others, being identified based on opinion, not fact.

Voter ID is not necessarily a bad thing and doesn't necessarily lead to suppression you just also need balances like making it mandatory for citizens over 18 to be enrolled to vote - that's what we do in Australia and it solves a whole bunch of issues.

You don't get problems with large swaths of demographic groups being disenfranchised/turned away from the polls, because everyone is on the electoral roll.

And oh look, this is how a technical discussion about voting machines will drift in to non-technical political discussion. Viva la detox week I say.
