The travelers had to stop at a checkpoint to show their identification.
Checkpoint → It is formed from "check" (from Old French *eschequier*, meaning to inspect or verify) and "point" (from Latin *punctum*, meaning a dot or a specific location). The word "checkpoint" refers to a specific location where verification or inspection occurs.
Think of a place where you 'inspect' ('check') something at a specific 'location' ('point') — that's what a checkpoint is.
