|The act of an agent communicating (service provider, social media, etc) their arrival by registering/confirming for a previously reserved service (e.g. flight check in) or at a place (e.g. hotel), possibly resulting in a result (boarding pass, etc).|
- CheckOutAction: The antonym of CheckInAction.
- ArriveAction: Unlike ArriveAction, CheckInAction implies that the agent is informing/confirming the start of a previously reserved service.
- ConfirmAction: Unlike ConfirmAction, CheckInAction implies that the agent is informing/confirming the start of a previously reserved service rather than its validity/existence.
