Digital Key
A virtual car key stored on a smartphone or wearable device that replaces physical keys.

Digital keys use encrypted wireless communication, such as Bluetooth Low Energy (BLE), NFC, or Ultra-Wideband (UWB), to unlock and start vehicles securely. Users can share limited-access keys remotely for delivery or rental services. Integration with mobile authentication enhances security, preventing cloning or unauthorized access. As part of connected mobility, digital keys provide convenience, personalization, and integration with smart ecosystems.
