Northern Computers' Wiegand readers are virtually maintenance-free. With Northern's Wiegand readers you will have no continuing maintenance, repair or replacement costs.

Wiegand readers offer high reliability, high security and flexibility at a reasonable cost. These readers can be used anywhere, regardless of the environment. Snow, rain, or extreme temperatures will not affect a Wiegand-based reader. Wiegand readers are not affected by radio frequency interference or external magnetic fields. You can place complete confidence in the ruggedness and reliability of these readers.

Wiegand technology consists of a series of specially treated wires which are embedded in each card. This proprietary manufacturing process, gives the treated wires unique magnetic properties. When the card is passed through the Wiegand reader, a sensing coil picks up the card number in the card. The reader then transmits the card number to Northern's access control system for processing.
