Abstract
Systems, devices, and related methods for shaping near field interrogation signals are discussed herein. Some embodiments may provide for a printer that includes a housing and a beam shaping near field communication (NFC) device secured with the interior surface. The beam shaping NFC device may include a ferromagnetic component including a core portion and a bottom flange portion. The beam shaping NFC device may further include a wire coil disposed around the core portion. The ferromagnetic component may concentrate near field interrogation signals generated by the wire coil toward a near field interrogation region and away from nearby conductive components, such as the interior surface of the printer.
