Abstract
A radio frequency identification (RFID) system comprises a reader, a memory, and a processor. When initiated, the reader receives an identification code of a first tag within a wireless communication range. The memory stores a time setting and an identification code of a second tag. The processor initiates the reader at a predetermined time indicated by the time setting, thus to determine whether the second tag exists in the wireless communication range.
