1. A touch sensor system comprising:
a touch sensor;
a drive-sense circuit (DSC) operably coupled to the touch sensor, wherein, when enabled, the DSC is configured to:
drive a first signal via a single line coupling to the touch sensor and simultaneously sense, via the single line, change of the first signal that is based on a second signal coupled to the touch sensor from a user that changes an electrical characteristic of the touch sensor, wherein the second signal is uniquely associated with the user; and
process the first signal to generate a digital signal that is representative of the electrical characteristic of the touch sensor;
memory that stores operational instructions; and
a processing module operably coupled to the DSC and to the memory, wherein, when enabled, the processing module is configured to execute the operational instructions to process the digital signal to detect interaction of the user with the touch sensor and to identify the user.
