1. A radio frequency identification (RFID) system, comprising:
- a reader, when initiated, receiving an identification code of a first tag within a wireless communication range;
a memory storing a time setting and an identification code of a second tag, wherein the time setting indicates a plurality of sessions in a schedule, each session corresponds to identification codes of a plurality tags respectively attached to a plurality of objects; and
a processor initiating the reader at a predetermined time indicated by the time setting, thus determining whether the second tag exists in the wireless communication range.

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.

11. A radio frequency identification (RFID) system, comprising:
-
a reader, when initiated, receiving an identification code of a first tag within a wireless communication range; a memory storing an identification code of a second tag and a time setting, wherein the time setting indicates a plurality of sessions in a schedule, each session corresponds to a table, each table comprises a priority number, name, and tag identification for each of objects; an inertial motion sensor detecting motion of the RFID system; and a processor initiating the reader based on the motion detection by the inertial motion sensor to determine whether the second tag exists in the wireless communication range. - View Dependent Claims (12, 13, 14, 15, 16)

17. A radio frequency identification (RFID) method, implemented in an RFID system, comprising:
-
storing a time setting and an identification code of a first tag in the RFID system, wherein the time setting indicates a plurality of sessions in a schedule, each session corresponds to identification codes of a plurality of tags respectively attached to a plurality of objects; initiating a reader of the RFID system on a predetermined time indicated by the time setting; receiving an identification code of a second tag within a wireless communication range of the reader; and comparing the identification codes of the first and the second tags to determine whether the first tag exists in the wireless communication range. - View Dependent Claims (18, 19, 20, 21, 22)
