How it's used
Commonly used in professional or academic settings to track attendance, but it has also evolved in online contexts to mean checking in on social media or apps. It implies a formal or semi-formal action of confirming one's presence at a specific time or location. Unlike simply saying hello, it carries the weight of an official record.
Examples
Remember to sign in when you get to the office.
Have you signed in for the event today yet?

Common mistake
Do not confuse this with 簽名, which simply means to sign one's name. 簽到 specifically refers to the act of signing in for attendance or arrival, whereas 簽名 can be used for autographs or signing documents.
