System and method for implementing reliable short-range communication by detector array

Abstract

A system (10) for realizing the reliable near field communication by utilizing a detector array is characterized in that the system (10) comprises a radio frequency mobile terminal (12) containing a radio frequency SIM card (11) and a radio frequency control terminal (13); a method comprises the following steps: a communication state database of each type of the radio frequency mobile terminal (12) is established; the communication between the radio frequency mobile terminal (12) to be tested and the radio frequency control terminal (13) is carried out, the radio frequency mobile terminal (12) carries out the communication with a plurality of groups of detectors (131) of the radio frequency control terminal (13) at a certain testing distance; the actual test results and the situations recorded by the communication state database are compared, therefore, the approximate range of the communication distance between the radio frequency mobile terminal (12) and the radio frequency control terminal (13) is judged. The method and the proposal of the invention can allow the data communication distance between a radio frequency communication terminal and a radio frequency communication device to be reliably controlled in the near field range, thereby ensuring the transaction safety and fundamentally ensuring the reliability of the communication.

Description

technical field [0001] The present invention relates to a record carrier for use with a machine, in particular to a record carrier with semiconductor circuit elements, and in particular to a system and method for controlling the radio frequency communication distance of a mobile terminal.
