Which Continuity feature allows you to scan documents or take photos with your iPhone and have them appear instantly on your Mac?

The feature that enables you to scan documents or take photos with your iPhone and have them instantly appear on your Mac is known as Continuity Camera. This powerful capability is part of Apple's Continuity suite, which aims to create a seamless workflow across Apple devices. By using Continuity Camera, users can leverage their iPhone's camera directly within apps on their Mac, such as Notes, Pages, or Mail.

When you choose to use the Continuity Camera option within a supported app on your Mac, your iPhone will activate its camera, allowing you to take a photo or scan a document. Once captured, the image or scanned document automatically transfers to your Mac, providing an efficient and intuitive way to include visual content without the hassle of manual file transfer.

Other options like Notes can certainly utilize the Continuity Camera feature to insert images, but they do not represent the entire capability on their own. Similarly, Universal Control is a feature that enables a single keyboard and mouse to control multiple devices, which, while useful, does not relate to scanning or taking photos. Continuity Scan is not a recognized feature in Apple's Continuity framework as of the provided context. Therefore, Continuity Camera is the precise term that accurately describes the functionality in question.
