An NFC wall reader is a compact, wall-mounted device designed to read data from Near Field Communication (NFC) cards, tags, or mobile devices. It is commonly used in access control systems, allowing secure and contactless identification of users. When a compatible NFC-enabled device is brought near the reader, the system authenticates the credentials and grants or denies access accordingly.

An NFC desktop reader is a compact, USB-connected device designed for reading (and often writing) data from NFC cards, tags, or compatible smartphones. These readers are typically used at workstations for identity verification, secure login, card registration, or other contactless data exchange applications.

An NFC controller is a central device in an access control system that processes and manages data received from NFC readers. It acts as the “brain” of the system, verifying user credentials, managing access rights, and controlling connected devices such as doors, gates, or turnstiles.

The ONYX NFC Controller is a high-performance access control unit designed to manage and authenticate users via NFC technology. As a core component in the ONYX access control ecosystem, it connects to NFC wall or desktop readers to verify credentials, enforce access permissions, and ensure secure entry across various zones.

Beyond readers and controllers, a range of NFC-compatible devices and accessories are used to enhance or support NFC systems. These components play vital roles in identity management, data transfer, and system customization in both personal and enterprise environments.
