System and method supporting close and remote communication in the same time

Abstract

Disclosed is a system which supports the short-range communication and the long-range communication simultaneously, comprising a mobile terminal (101), a short-range communication POS machine (102) or a long-range communication POS machine (103), a background authorizing server (104), an authorization distributing channel (106) and an RF interface (105); the background authorizing server (104) transmits the key information to the mobile terminal (101) through the authorization distributing channel (106); the background authorizing server (104) transmits the identity identification code to theshort-range communication POS machine (102) or the long-range communication POS machine (103) through the authorization distributing channel (106); the mobile terminal (101) completes the data exchange with the short-range communication POS machine (102) or the long-range communication POS machine (103) through the RF interface (105). The communication system in the invention is adopted to support the short-range communication or the long-range communication simultaneously with a unified frequency range; meanwhile, the security of the communication and the transaction under the two communication modes is guaranteed.

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 more particularly to a system and method for supporting both short-range and long-range communications. Background technique [0002] The traditional contactless smart card uses a communication frequency of 13.56MHz. In view of the low operating frequency, its communication range is limited to a very short distance, generally below 10cm, but the communication distance required for expressway entrances and exits and airports is relatively long (several meters) and more than tens of meters), the automatic toll collection system needs to use higher frequency to complete the communication at such a distance, and the 5.8GHz frequency band is commonly used at present. With the popularization of mobile terminals, adding radio frequency communication modules for cash payment and transactions on the mobile terminal...

AI Technical Summary

Problems solved by technology

[0009] 1. Communication based on the 13.56MHz frequency band, because the frequency is low, it is difficult to achieve long-distance communication;

[0010] 2. Using the method of simple combination of two frequencies to achieve long-distance and short-distance communication at the same time, it cannot ensure the safety of the system and complete data sharing, and has little practical significance
