Key Fob Description:
A key fob is a small-sized hardware device that has built-in authentication mechanisms designed to control and secure access to network services or data. These compact devices traditionally feature remote control capabilities and are primarily used for car keyless entry systems, apartment buildings, and office security systems.
Key fobs commonly use radio frequencies to communicate with various devices like cars and building access systems. It typically houses an electronic chip that communicates with the security mechanism or decides the cryptographic algorithms to authenticate a user. Most key fobs have physical keys for backup if the battery dies or if the technology malfunctions.
Key fobs designs vary widely, with some resembling small remote controls, while others adopt a traditional key's look. They often come with buttons that activate different functions, like locking and unlocking doors or activating the alarm system.
