Digital Car Key

The digital car key is an emerging area of identity authentication.

The development of science and technology has made intelligent electronic modules widely used in the automotive field. Digital car key has become an important technical direction of the intelligent experience of human-vehicle interaction, and its main functions include remote control key, operation-free entry + one-key start, non-inductive control car, key sharing, etc., these functions are based on cryptography technology, with the help of various communication methods, and realized in rich physical forms. Watchdata has a production base that meets IATF16949 certification and provides one-stop digital car key solutions and products.

UWB positioning module products are divided into two types: Multi-node UWB module and Single-node UWB-AOA module.
Single-Node UWB-AOA Module

The UWB-AOA digital key solution uses a single node UWB-AOA to achieve UWB positioning. The principle is to achieve spatial measurement of distance by UWB and three-dimensional angle measurement by AOA antenna array, so as to calculate the key position. It has obvious cost advantage compared with UWB multi-node scheme.
