Abstract

The invention discloses a method, a subscriber identity module card and a system used for sending messages. According to the method used for sending messages, the state is converted from a dormant state into a standby state when wake-up information sent by a reader-writer is received, the waiting time is randomly selected within a predetermined time range, and data information is sent to the reader-writer when the waiting time is up. Through communication in an asynchronous transmission mode, the card reading efficiency and accuracy of the reader-writer are improved, and the occurrence of missed card reading is effectively avoided.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for sending information, a user identification card and a system. Background technique [0002] With the popularization of 3G communication network and the introduction of the latest 4G network, the speed of wireless network communication is getting faster and faster, mobile devices are becoming more and more popular, and mobile phones have gradually become the main terminal for people to connect with information technology. The country began to implement the telephone real-name system on September 1, 2013. The communication card of the telecom operator (ie UIM (User Identity Model, User Identification Module), SIM (Subscriber Identity Model, Customer Identification Module)) was installed in the mobile phone. The carrier of the communication card, which represents the characteristics of personal identity ID, is becoming more and more prominent. [0003] In the various informat...
