Radio-frequency identification based object selection method

Abstract

The invention discloses a radio-frequency identification based object selection method, comprising the steps that: step 1, a corresponding electronic tag is generated according to an information sheet of objects, and a communication password is generated at the same time; step 2, the communication password is sent to a mobile phone of a recipient; step 3, a plurality of objects are distributed into a sending-receiving location in a unified way, and the recipient inputs the communication password into a handheld card reader to enable the handheld card reader to be in communication connection with the electronic tag on the target object; step 4, after the recipient confirms object information on the handheld card reader, the handheld card reader emits a distance measurement signal, the handheld card reader emits sounds of different frequencies according to different measurement distances, and the shorter the measurement distance is and the higher the sound frequency is; and step 5, the handheld card reader locates the target object and selects out the target object according to the sound frequencies in the step 4. The method solves the problem of difficulty in accurate positioning and selection of the target object.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to an object selection method based on radio frequency identification. Background technique [0002] The radio frequency tag is the physical carrier of the electronic product code (EPC), which is attached to the trackable item and can be circulated globally and identified, read and written. RFID (Radio Frequency dentification) technology, as a key technology to build the "Internet of Things", has attracted people's attention in recent years. RFID technology originated in the United Kingdom and was used in World War II to identify enemy and enemy aircraft. It was commercially used in the 1960s. RFID technology is an automatic identification technology. The U.S. Department of Defense stipulates that after January 1, 2005, all military supplies must use RFID tags; Counterfeit medicines. A series of actions such as the application of RFID technology in Walmart ...
