Abstract: A shopping assistance system includes a moving device (bagging device) and an information acquisition device. The moving device includes a support portion and a guide portion. The support portion is provided with a placement surface on which a product with an RF tag is placed. The guide portion includes a shielding space for shielding radio waves therein, and is disposed around the support portion along outer circumferential edges of the placement surface. The information acquisition device reads product information from the RF tag by performing wireless communication with the RF tag using an antenna when a relative positional relationship between a communication area of the antenna and the RF tag changes in the shielding space, the communication area being an area which is set around the antenna and in which wireless communication with the RF tag is performed.
