Double Headed Bar Code Reader
Omni Duo Specifications

A unique dual-head design reduces the confusion at the point of swipe by accepting cards being swiped regardless of the magnetic stripe orientation. Two magnetic heads provides the most convenience to the user and ensures the data is captured on every swipe. The Omni Duo delivers exceptional performance in a compact solution.

The Omni Duo reader is originally designed for the demanding Access Control and Time & Attendance markets. Its die cast metal base, stainless steel wear plate, and impact-resistant housing make Omni Duo ideal for the growing market of self-service and un-attended applications. The Omni Duo reads up to three tracks of magnetic information with a single swipe in either direction. Omni Duo reads most bar code symbologies; both visible or infrared bar code data and/or MagStripe data, both in a single swipe. It has a beeper and three-color LED indicator to signal a successful read. The reader is programmable so that the data format and intelligent interface output can be programmed & configured to match application communication requirements.

The Omni Duo reads up to 3 tracks of information with a single swipe in either direction. In combination, the same Omni Duo unit can read both bar code and MagStripe media. It scans bar codes printed on paper, card stock, or plastic. An infrared option is available for security-based applications, where bar codes are over-printed to prevent duplication. The data outputs are TTL, RS232, keyboard wedge, USB/KB, USB/RS232, and Wiegand interfaces.

The Omni Duo’s output can be formatted with terminating characters, special preamble and/or postamble character strings, and special parsing to match the data format expected by the terminal. These settings are programmed into the reader and stored in non-volatile memory.

The Omni Duo reader is designed for demanding applications, such as for access control or in self-service kiosks. Its die-cast metal base, stainless steel wearplate, and impact-resistant housing make it ideal for stand-alone, high-volume applications. Its metal base can be securely mounted with screws, and cable exits are available at the side, end, or bottom of the unit. Weatherproof, sealed, or extended temperature versions are available for use in harsh environments.
