AI summary

A data storage device includes a reader/writer for communicating wirelessly with an radio-frequency (RF) tag and a memory storing parameters in association with characteristic information of the RF tag. The parameters are used in communicating wirelessly with the RF tag. A sensor is configured to obtain characteristic information of the RF tag. A processor acquires the characteristic information of the RF tag through the sensor and a parameter corresponding to the acquired characteristic information from the memory. The processor then communicates wirelessly with the RF tag through the reader/writer according to the acquired parameter.
