Document Type and Number:
WIPO Patent Application WO/2021/164024
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are an item positioning method, a terminal, a passive RFID tag, and an RFID card reader. The method comprises: a terminal emits a continuous wave (CW) to a passive radio frequency identification (RFID) tag. The CW is used to provide energy to the RFID tag, the passive RFID tag is disposed on an item, and the energy is used for an RFID card reader to communicate with the passive RFID tag on the basis of backscatter so as to position the item. By using embodiments of the present application, the reading distance of a passive RFID tag can be effectively increased.
