Title:
TAG IDENTIFICATION AND INVENTORY METHOD AND APPARATUS, READER, MEDIUM AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/189248
Kind Code:
A1
Abstract:
The present disclosure relates to a tag identification and inventory method and apparatus, a reader, a medium and a computer program. The tag identification method comprises: a tag signal receiving step, involving: receiving tag signals in a time slot; and a signal processing step, involving: determining whether tag collision occurs in the time slot, and if it is determined that tag collision has occurred, selecting a tag signal from among the received multiple tag signals to identify a corresponding tag, and recording the number of unidentified tags in the time slot.
