Yes, the UWB digital key requires hardware support. Ultra-Wideband (UWB) technology is a wireless communication technology that transmits and receives broadband and low-power pulse signals to accurately locate positions. A UWB chip needs to be integrated in a smart device to play the function of a digital key. In addition, UWB digital keys also need the support of mobile phone manufacturers and system upgrades to achieve intelligent car locks, access control and other functions. Therefore, the UWB digital key needs the support of hardware and software manufacturers in order to promote the application.
