Document Type and Number:
WIPO Patent Application WO/2022/083523
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of near-field communications. Provided is a control method and system for preventing incorrect identification in near-field transmission, and an electronic device and a medium. A near-field transmission card search source and a near-field transmission label are provided. The near-field transmission card search source sends a card search signal according to a certain card search period, the card search period comprising a first card search period and a second card search period. A card search failure mark is provided in the near-field transmission card search source, the card search failure mark comprising an initial state. The method comprises: a near-field transmission card search source sending a first card search signal at the start of a first card search period; if a first feedback signal is not received within a card search duration, changing a card search failure mark from an initial state to a first state, and also determining the card search period to be a first card search period; the near-field transmission card search source sending a second card search signal after the first card search period; and if a second feedback signal is received within a card search duration, changing the card search failure mark to the initial state, and changing the card search period to a second card search period.
