This disclosure describes a mechanism for improving point-of-sale (POS) check reader performance by automatically postioning displays (which may cause interference) away from the reader. CRT displays generate magnetic fields which can interfere with the operation of magnetic ink character recognition (MICR) devices that are commonly used in the retail environment to input account information from personal checks. This interference results in an increase in the number of unreadable checks. The closer the display is to the reader the larger the effect. Typically, POS displays are installed on adjustable mounts. This allows a cashier or customer to unwittingly degrade MICR reader performance when the dislplay is readjusted closer to the reader. In this disclosure, a motor and some logic is added to the monitor mount such that the display can be repositioned under software control. Signal interference and signal strength data is gathered from the MICR reader by a controller. The controller can then reposition the monitor until the intereference is reduced to acceptable levels. The CRT can be mounted either on the right or the left side of the reader. If signal interference increases when the display is initially moved, then the controller knows that the display has moved closer to the reader and that the display must be repositioned in the opposite direction. The CRT can be returned to its original position after the check reading operation. As shown in Fig1. The POS system has a monitor (3) that is mounted to a base (1). The monitor can swivel right and left on turn table
