Aliro

An open standard for secure mobile access control using smartphones and wearables

Aliro is a standardized communication protocol developed by the Connectivity Standards Alliance (CSA) that enables interoperability between mobile devices, wearables, and access control readers from different manufacturers. The standard defines how smartphones and wearables can securely replace physical keys for unlocking doors and entry points in both residential and commercial applications.

The protocol supports multiple wireless technologies, including Bluetooth Low Energy (BLE), Ultra-Wideband (UWB), and NFC, allowing developers to choose the appropriate technology for their specific use case.

Nordic Semiconductor is actively involved in the development of the Aliro standard and provides complete hardware and software solutions for building Aliro-compliant access control devices.

Aliro Early Access

Development Software

The Aliro software for Nordic's nRF Connect SDK is currently available to early adopters. The software is provided as an nRF Connect SDK add-on, enabling seamless integration with Nordic's existing development tools and workflows.

If you are interested in accessing the Aliro software before the public release, you must be a member of the CSA at least at the Participant tier, as well as a member of the CSA Aliro Working Group. Contact Nordic Semiconductor to discuss access requirements and membership options.

For developers who are not yet eligible for access, the software will be publicly available in Q1 2026. At that time, it will be accessible through the standard nRF Connect SDK distribution channels.
