thumbprints

Unique digit traces

Thumbprints are impressions left by the thumb, used for identification since the ridged patterns are unique to each person.

Police collect thumbprints at crime scenes; documents may require a thumbprint for verification.

The word also names a type of cookie with an indentation pressed into the center: She filled the thumbprints with raspberry jam.
