The HID Omnikey 5427 CK is a dual-frequency card reader that handles both low and high-frequency credentials — the kind of device that suits organisations running mixed card environments without wanting to manage two separate readers. It supports HID mobile credentials via a Bluetooth interface, which means staff can present access credentials from a smartphone rather than a physical card.

The directional antenna is worth noting: it reads access credentials from up to 2 metres away, giving a degree of practical flexibility in how and where it's deployed. For integrators building custom access solutions, it's also available as a reader board for embedded applications. Data structure and output mode configuration is flexible, which helps when fitting the reader into an existing system rather than rebuilding around it.

A solid choice for access control projects that need to bridge legacy card technologies with modern mobile credential infrastructure — without compromising on either.
