Abstract

The invention provides a mobile payment system, a card reader, a mobile payment terminal and a distance measuring method thereof. The mobile payment system comprises the mobile payment terminal and the card reader, a probe light generating module, a probe light detecting module and a master control module are arranged in one of the mobile payment terminal and the card reader, wherein the probe light generating module transmits probe light to the other one of the mobile payment terminal and the card reader, the probe light detecting module is used for detecting probe light reflected by the other one of the mobile payment terminal and the card reader, and the master control module is used for confirming the distance between the mobile payment terminal and the card reader according to transmission time of the probe light. According to above structure, the distance between the mobile payment terminal and the card reader is measured according to the transmission time of the probe light, more accurate judgment on distance can be made, and thus communication distance of mobile payment is controlled.

Description

【Technical field】 [0001] The invention relates to the communication field, in particular to a mobile payment system, a card reader, a mobile payment terminal and a distance measurement method. 【Background technique】 [0002] Mobile payment, also known as mobile payment, is a service that allows users to use their mobile payment terminals (usually mobile phones, but also PDA (Personal Digital Assistant, handheld computer), etc.) to pay for the goods or services they consume. Way. At present, the main mobile payment technologies in the world are mainly divided into: NFC (Near Field Communication, short-range wireless communication technology), eNFC (enhanced Near Field Communication, enhanced short-range wireless communication technology), SIM-PASS (mobile phone card reading system) ), RFID-SIM (dual-interface smart card), RFID-SD, etc. [0003] In the process of mobile payment, the distance between the mobile payment terminal and the card reader must be controlled, for exam...
