The adoption of digital key technology in smart buildings is fundamentally reshaping access control and identity authentication systems. UWB's superior accuracy and anti-relay capabilities are gradually replacing legacy NFC and Bluetooth solutions, driving demand for advanced positioning chips and secure authentication modules. Regulatory tightening on data sovereignty and privacy will raise compliance costs, especially for biometric data handling and secure storage. Market consolidation is expected, with leading players likely to acquire or develop proprietary security chips, while smaller firms face technological obsolescence risks. Over the next 12–24 months, the convergence of UWB and Bluetooth Channel Sounding will unlock cross-industry applications, particularly in healthcare and warehousing, where safety and operational efficiency are paramount, creating new competitive advantages and market opportunities.
