Fingerprinting for I-485 Passport Stamping

[ForrestGump]

Do anyone know which fingers do they take for fingerprinting when you go for passport stamping?.

I heard some say THUMB fingers, some say just index fingers. Any guys who went recently to get stamping, can you post here the details.

Thanks,
