Abstract:
A data input apparatus that obtains information relative to an object, the apparatus comprising:a processor;a two-dimensional image capture device coupled to the processor;a memory coupled to the processor and storing an image of at least an image of a two-dimensional machine-readable symbol on the object, and wherein the two-dimensional machine-readable symbol stores data corresponding to response characteristic information versus position for at least one resonator secured to the object;a wireless data transceiver coupled to the processor, wherein the wireless data transceiver transmits an energizing signal to, and receives electromagnetic data received from, the at least one resonator secured to the document; andwherein the memory stores instructions for the processor for (a) determining an orientation and decoding the image of the two-dimensional machine-readable symbol to obtain at least the response characteristic information, (b) processing the received electromagnetic data, and (c) correlating the response characteristics with the received electromagnetic data.
