After watching this a few times, I don't think she was taking pics of the ballots. I think she was just on the phone.

She's wearing clothes that look like scrubs and has a lanyard with a key around her neck.

Speculation: This is a supervisor at a medical facility of some sort.

Maybe a nursing home, home for the disabled or something similar.

Key could be for the drug cart or something like that.

She's harvesting the ballots of the patients.>>16318082

She would have been paid by whoever hired her at the facility. Different system.
