The invention discloses an information interaction system and a processing method based on wireless access device identity (ID) identification. The information interaction system comprises an information storage server, a wireless access device, a mobile terminal and an information entry terminal, wherein the mobile terminal scans the wireless access device to extract device ID which is then sent to the information storage server, and then corresponding preferential information through matching according to the device ID is obtained and sent to the mobile terminal to be displayed. According to the information interaction system and the processing method based on wireless access device ID identification, the corresponding preferential information is searched through scanning of the wireless access device by means of uniqueness of device ID, thereby, store preferential information of a nearby area can be obtained, positioning steps and time of the mobile terminal are omitted, and the problem caused by positioning accuracy is avoided. Besides, one or more devices among a wireless fidelity (wifi) device, a bluetooth device, an infrared device, a radio wave transceiver or an ultrasonic device can be used as the wireless access device so that requirements at different occasions can be met. The technical problem that locating information is required to push messages in terms of existing information issue technologies is excellently solved.
