65 USD for a passport card (2) (the cheapest passport option).

Both require attending in-person appointments.

For contrast:

Voting is compulsory in Australia. Citizens may register to vote entirely online, and may prove their identity using a Medicare card or citizenship certificate (or driver's license or passport, ofc) (3). (Aside: this page of FAQs explicitly calls out that these two means of proving ID have been added as a response to increasing feedback from young people, disabled people, and people living in remote areas about having less access to driver's license or passport.)

Obtaining an Australian Medicare card is free, and citizens may prove their identity using a birth certificate (no need for it to be certified) and submitting their application + supporting documents by email (or by mail, but that costs postage) (4).

Free, and no in-person appointment.
