Setting up smart home devices can be hard. A NFC chip lets users connect devices quickly, with one tap, even if they have no batteries.

Setting up smart home devices can be slow, frustrating, and insecure. You might struggle to connect lights, cameras, door locks, and other IoT devices because conventional methods like Bluetooth pairing or QR codes are often unreliable, cumbersome, or impossible in certain situations. Adding multiple devices at once, especially unpowered ones, adds even more complexity. Security is also a concern, as poorly secured connections leave smart homes vulnerable to unauthorized access.
STMicroelectronics’ ST25DA-C NFC chip addresses these issues by making smart home device setup faster, simpler, and more secure. Using the NFC technology found in most smartphones, users can add devices to their home network with a single tap. The chip can perform the cryptographic operations required for Matter device commissioning using energy harvested from the NFC field, enabling even unpowered devices to be added easily. This allows multiple accessories to be installed in parallel without extra effort.
Security is built in from the ground up. The chip protects devices through authentication and secure storage of cryptographic keys, certificates, and network credentials. Its hardware is Common Criteria-certified and designed to meet GlobalPlatform Security Evaluation Standards for IoT platforms, giving users confidence that their smart home network is safe.
“The integration of NFC-based onboarding in Matter 1.5 is a timely enhancement to the smart home experience. Our market-first ST25DA-C chip leverages this capability to simplify device commissioning through tap-to-pair functionality. This reduces setup complexity, especially for installations that are difficult to access, thanks to NFC-enabled battery-less connectivity. This aligns well with the broader momentum in the smart home market to serve consumers who increasingly prioritize ease of use, interoperability, and security. NFC-enabled Matter devices are positioned to play a key role in driving even greater adoption,” said David Richetto, Group VP, Division General Manager, Connected Security at STMicroelectronics.
