  • Publication number: 20240013183
    Abstract: A Projected Capacitive (PCAP) display including multiple arrays of conductive electrodes performs a dual function. In a first function, the PCAP display uses the conductive electrode arrays to generate an electrostatic field and determines the presence and position of a conductive object based on small changes it detects in the capacitance of that electrostatic field. In a second function, the PCAP display uses the same conductive electrode arrays to generate a magnetic field. As a user swipes the card across the surface of the PCAP display, it causes small changes in the generated magnetic field. The PCAP display retrieves the data magnetically encoded onto the magnetic stripe card based on the changes it detects in the magnetic field.
