Abstract
Read head array stitching techniques are described. A card reader includes an array of magnetic sensors (a read head array) for retrieving account information from a magnetic stripe of a financial transaction card. The magnetic sensors can be arranged in rows and columns. During a card swipe, each magnetic sensor receives a series of readings. A processor determines relative bit rates for each series of readings. The processor determines which sensor corresponds to which track of the magnetic stripe based on a comparison of the relative bit rates. The processor generates a data stream for at least one track based on portions of readings from each sensor during periods of time the sensor is determined to correspond to the track.
