1. A method of identifying a location of a data tag, the method comprising:

  • reading the data tag by a data tag reader module of a portable data tag reader device that includes operatively coupled components comprising an ultrasonic transducer, the data tag reader module, an orientation module, a data transmission interface, a reader device processor, and a memory;

    determining, by the reader device processor, a read zone of the portable data tag reader device relative to the portable data tag reader device at least in part using data from the orientation module;

    transmitting, by the reader device processor and the data transmission interface, characteristics of the read zone;

    receiving the characteristics of the read zone from the portable data tag reader device on a data reception interface of a server operatively coupled to the portable data tag reader device, wherein the server includes operatively coupled components comprising an ultrasonic module operatively coupled to the ultrasonic transducer of the portable data tag reader device, the data reception interface, a server processor, and a memory;

    determining, by the server processor, the location of the portable data tag reader device at least in part using the ultrasonic module; and

    determining, by the server processor, the location of the data tag using the location of the portable data tag reader device and the read zone of the portable data tag reader device.
