Method and system for third-party account automatic teller machine withdrawal based on dynamic two-dimensional code

Abstract

The invention relates to the technical field of encoding and decoding two-dimension codes, in particular to a third-party account ATM (automatic teller machine) withdrawing method based on dynamic two-dimension codes. The method comprises the following steps that a user can choose a third-party organization no-card withdrawing function of the dynamic two-dimension codes on an ATM, the ATM can display dynamic two-dimension code images, the user can log in third-party organization APP application programs to scan the dynamic two-dimension codes and send transaction data information to a third-party organization server, the third-party organization server can transmit the transaction data to a dynamic two-dimension code checking server, the dynamic two-dimension data checking server can check data and finally returns the transaction information to the third-party organization server, and the third-party organization server can check the legality of the transaction information and then checks the transaction information again. When the transaction information is not legal, transaction is refused and finishes. Compared with an existing static two-dimension code withdrawing program, a dynamic two-dimension code checking technique utilizes a more complex security mechanism to guarantee financial security of the user.

Description

technical field [0001] The invention relates to the technical field of coding and decoding of two-dimensional codes, in particular to a method and system for withdrawing cash from an automatic teller machine for a third-party account based on a dynamic two-dimensional code. 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 sta...
