Aliro products

Aliro is an industry-standard access credential and communication protocol, ensuring a secure and consistent experience across user devices to unlock points of entry, defined by the Connectivity Standards Alliance (CSA). STMicroelectronics is a board member of the CSA and provided technical expertise to develop the Aliro 1.0 specification. ST offers complete solutions for Aliro platform development.

This standardized communication protocol revolutionizes access control by enabling seamless interactions between different reader architectures and mobile devices with user credentials.

For device manufacturers, Aliro supports various architectures, reduces integration complexity, and administers a certification program to ensure interoperability.

Connectivity options

Aliro defines three configurations with different connectivity technologies to enable a secure and contactless exchange of credentials between user devices (e.g. mobile, wearable device, orsmartcard) and reader devices (e.g. access control readers and locks on doors and openings).

Near Field Communication (NFC), for contactless tap-and-go access use cases
NFC + Bluetooth^® Low Energy (LE), for access control use cases
NFC + Bluetooth^® LE + ultra-wideband (UWB), for hands-free access use cases enabled by secure UWB ranging

Aliro solution architecture with:

A complete solution for secure access control with NFC connectivity includes a reader device with connectivity & security building blocks that exchanges credentials with a user device (such as a mobile, wearable device, or smartcard).

How does Aliro work with Matter?

Aliro specifies the secure use of a mobile phone or wearable device as a key for access enablement. Matter defines how connected products communicate with each other, enabling a wide range of command-and-control smart home use cases. Aliro and Matter standards are complementary and operate independently from one another. Devices and readers may support either one or both protocols.
