Data transmission methods, communication equipment, and storage media

Abstract

The invention relates to a method of data transmission, an answering device, a reading / writing device, a storage medium, and a communication system for accessing a write card. The proposed method comprises the following steps: The answering device receives the first signal sent by the reading / writing device (301). The first signal carries destination flag information. The destination information is used to identify the answering device. The first flag information of the answering device matches the destination flag information. The answering device identifies the first slot, and sends the first access information to the read / write device in the first slot (305) * According to the proposed method, the first slot is identified, to avoid collisions of different slots in the same slot in the next round, reducing the probability of collisions, and improving the performance of write access.
