Here is an excerpt
A. Are there restrictions on the voter registration drive offering something of value to a person in
exchange for completing a voter registration application?
It is a felony under New York law to pay, lend or contribute, or offer or promise to pay, lend or contribute any money or other valuable consideration to or for any voter, or to or for any other person, to induce such voter or other person to place or cause to be placed or refrain from placing or causing to be placed
his name upon a registration poll record.14
Federal law states that whoever pays or offers to pay or accepts payment either for registration to vote or for voting shall be fined not more than $10,000 or imprisoned not more than five years. 15 At least one federal appellate court has interpreted payment as intended to include forms of pecuniary value offered or given directly to an individual voter, and indicated the value should be based on an assessment of the monetary worth of an item from the perspective of the voter receiving the item. That case held that food vouchers could be payment.16
