A merchandise discharge device body has a detection means for directly or indirectly detecting discharge of merchandise and an RFID (Radio Frequency Identification), where the merchandise discharge device body transmits power of an operation member operated by a user to a discharge member, operating the discharge member to discharge the merchandise. The number of pieces of merchandise to be discharged, which number is obtained by the result of detection by the detection means, is stored in a semiconductor memory of the RFID. Merchandise management is performed by reading the merchandise data, stored in the semiconductor memory, by an external reader.
