Another note that New York is currently even weirder having only allowed same day voter registration on a single day of early voting rather than the entire period unlike North Carolina
They do require a valid ID, though, which can be a problem for some people. I don't know what their requirements are for "ID", but it's probably a driver's license or passport, or state-issued ID. These have all been shown to be barriers for certain groups of people.
In states that have voter registration, proof of identity often accepts more broad documentation: birth certificates, or other documents acceptable for what you'd need for a DL.
So, it's cool for everyone who has a driver's license, or a passport. Not so cool for folks who don't drive (because of a handicap, for instance). Convenient for many people, but not "based". Requiring ID at voting time is a tactic used to disenfranchise groups of people. Young urban voters, for instance, who may not yet have needed a license.
That's true. My state's voter ID law made my absentee ballot a huge pain in the ass.
