Beacon technology uses small wireless devices called beacons to transmit signals to nearby smartphones and tablets. These beacons utilize Bluetooth Low Energy (BLE) to communicate with devices, allowing them to send notifications, advertisements, or information based on a user's location. This technology is commonly used in retail, museums, and events to enhance customer experiences. When a smartphone comes within range of a beacon, it can receive messages or prompts tailored to its location. This enables businesses to engage customers with personalized offers or information, improving interaction and potentially increasing sales. Beacon technology is also used in navigation and location-based services.
