Near field payment connection and data exchange method and system

Abstract

The present invention provides a near-field payment connection and data exchange method and system. The method includes: 1) When it is detected that the distance between the mobile terminal with Bluetooth function and the Bluetooth payment peripheral is less than the near-field judgment start boundary threshold, execute Step 2); 2) Establish a Bluetooth connection when it is determined that the distance between the mobile terminal and the Bluetooth payment peripheral tends to decrease; 3) It is detected that the distance between the mobile terminal and the Bluetooth payment peripheral is less than the first payment boundary threshold , send a prompt message to the Bluetooth payment peripheral to confirm the corresponding payment; 4) exchange payment data; 5) disconnect the Bluetooth connection after judging that the data exchange is completed. The present invention integrates the time-consuming Bluetooth search, connection, data exchange, and Bluetooth disconnection with user actions by setting corresponding thresholds and according to the threshold judgment mechanism, so as to realize stable and reliable near-field payment of mobile terminals with Bluetooth functions , Fast and convenient connection and data exchange.

Description

technical field [0001] The invention relates to the technical field of mobile payment, in particular to a near-field payment connection and data exchange method and system for realizing fast and stable connection and data exchange in near-field payment by a Bluetooth-based mobile terminal. Background technique [0002] Mobile phone NFC (Near Field Communication, Near Field Communication) is a fast payment method that is already well known to everyone. NFC realizes the near-field payment process of the mobile phone is relatively simple. After the mobile phone enters the sensing area of ​​the payment peripheral NFC, the mobile phone and the payment device directly exchange data through NFC. An obvious feature of NFC payment is that when the mobile phone and the payment peripheral are quickly approaching, the payment can be realized quickly. However, for some mobile phones with a high market share, there is no integrated NFC function item; at present, Bluetooth technology has ...

AI Technical Summary

Problems solved by technology

If the data exchange is realized according to the standard Bluetooth search, judgment, connection, data communication, and disconnection methods, the payment time will be much longer than the NFC payment time, which is a big change for the existing application mode. , is not conducive to promoting

At the same time, because Bluetooth does not use NFC signal attenuation technology, there may be multiple Bluetooth BLE mobile phones or other Bluetooth BLE devices in a large range, and it may be impossible to determine which mobile phone or Bluetooth BLE device needs to exchange data during payment.
