Digital keys are virtual versions of traditional keys that allow users to unlock and access devices, vehicles, or buildings using smartphones or other digital devices. They utilize technologies like Bluetooth or NFC (Near Field Communication) to communicate with locks, providing a convenient and secure way to manage access without physical keys. These keys can be easily shared with others through apps, making it simple to grant temporary access to friends or family. Digital keys are commonly used in smart locks, automobiles, and mobile wallets, enhancing security and streamlining everyday tasks by reducing the need for physical key management.
