PROBLEM TO BE SOLVED: To provide a conveyance system which accurately obtains information from RFIDs respectively attached to pieces of baggage on a conveyor without significantly deteriorating the conveyance efficiency of the conveyor.SOLUTION: A conveyance system includes: a conveyor 101; a detection device 102 which detects a situation that a piece of baggage 200 is positioned in a communication position 121; a first antenna 131 which communicates only with an RFID 201 of the piece of baggage 200 existing in the communication position 121; a second antenna 132 which communicates with RFIDs 201 of pieces of baggage 200; communication means 104 which conducts communication through the first antenna 131 or the second antenna 132; control means 105 which outputs error information when the detection device 102 detects the situation that the piece of baggage 200 is positioned in the communication position 121 and communication of the communication means 104 with the RFID 201 is in bad condition or impossible; and switching means 106 which switches a state of the conveyance system into a state, in which communication through the second antenna 132 is possible, when the error information is output. |
