Passport Cards. Passports cards cost $30 for adults and $15 for persons under 18, plus a $25 execution fee for both adults and minors, according to the issuing agency, the U.S. Department of State, (travel.state.gov). Unlike passports, passport cards can be obtained on a same-day basis from regional passport agencies, listed on the site.
How much it costs: $135 for a passport, $110 for a renewal, $105 for a minor (under 16), $55 for a passport card (for entering the United States through land border crossings or sea ports-of-entry -- not for international travel via air). How long it lasts: 10 years (kids passports expire in five years)
