Method and system for withdrawing cash from bank automatic teller machine based on dynamic two-dimensional code

Abstract

The invention relates to the technical field of coding and decoding of two-dimensional codes, in particular to an automatic tell machine money withdrawing method based on a dynamic two-dimensional code. The method comprises the steps that 1, a dynamic two-dimensional code image is displayed on an automatic tell machine; 2, the dynamic two-dimensional code image displayed on the automatic tell machine is scanned through a mobile phone bank app on a mobile phone, and transaction data information is sent to a mobile phone bank server; 3, the mobile phone bank server transmits the transaction data to a dynamic two-dimensional code verification server; 4, the dynamic two-dimensional code verification server conducts data verification, decoding and time confirmation; 5, sending a data message to a prepositive server of the automatic tell machine in a packaged mode after a user inputs a corresponding bank card password into the automatic tell machine; 6, the prepositive server of the automatic tell machine feeds a responding message back, money comes out if the feedback process is normal, and a prompt message comes out to end the transaction otherwise. Compared with existing static two-dimensional money withdrawing processes, the dynamic two-dimensional code verification technology has the advantage that a more complicated safety mechanism is adopted, and therefore the financial safety of the user is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of coding and decoding two-dimensional codes, in particular to a method and system for withdrawing cash from bank automatic teller machines based on dynamic two-dimensional codes. Background technique [0002] At present, when people need to withdraw money on an ATM, they usually need to carry a bank card to operate on the ATM. However, in the process, they often forget to take out the card, swallow the card abnormally, the card reader fails to trade or various other problems. Such a withdrawal method is time-consuming and cumbersome to operate, and the user experience urgently needs to be improved. [0003] At present, some banks have also introduced the method of withdrawing money from ATMs without a card. For example, mobile phone appointment withdrawal, static QR code withdrawal, but the process of mobile phone appointment withdrawal is very cumbersome, and the security of static QR code withdrawal need...
