As the digital access control market, which uses smartphones or wearables as keys, shifts from an individual company-centric approach to one based on common standards, STMicroelectronics has stepped forward to support wireless and security technologies compliant with the Aliro standard. The company announced that it will support manufacturers of smart door locks and readers in designing interoperable products more quickly through related development tools and a semiconductor portfolio.

On the 27th, ST announced its achievements in contributing to the spread of Aliro-based access control technology. Previously, the Connectivity Standards Alliance (CSA) released the Aliro 1.0 specification on February 26. Aliro is a standardized protocol designed to enable digital devices to exchange access credentials.

Aliro is a structure that processes authentication between access devices and user terminals based on NFC, Bluetooth Low Energy (BLE), and Ultra-Wideband (UWB). NFC is used for short distances, BLE for wider ranges, and BLE and UWB can be used together for hands-free operation. Compared to existing mechanical keys, PIN pads, or contactless cards, it is characterized by ease of integration with the smartphone ecosystem and is advantageous for incorporating digital key functions such as permission settings, sharing, and privacy protection.

In this announcement, ST presented the X-CUBE-ALIRO software package and reference design (STEVAL-ALOCKCB) integrated into the STM32Cube. This software provides a reference implementation for reader devices that meets the technical and interoperability requirements defined in Aliro 1.0, while the reference design includes data necessary for board design, verification, and component configuration. Its primary purpose is to support accelerated time-to-market by reducing the design and testing burden during the early stages of development.

In terms of hardware, the ST25 NFC reader, Bluetooth-enabled STM32 microcontroller, UWB IC, and STSAFE-A security device were presented as the product family compatible with Aliro. Essentially, the system is configured to enable everything from tap-based access to long-range recognition, hands-free authentication, and digital key storage within a single component framework. The company explained that this configuration reduces the burden associated with RF design and certification processes, and facilitates compliance and interoperability testing.

At Embedded World 2026, Nukee Home Solutions showcased an Aliro-based solution incorporating ST’s NFC and UWB technologies. Although Aliro 1.0 has just been released, as semiconductor companies and lock manufacturers prepare for commercialization, there is a growing possibility that the digital access control market will shift from individual specifications to common standards.
