Embodiment Construction

[0034] The technical solutions of the present invention will be clearly and completely described below through specific embodiments in conjunction with the accompanying drawings.

[0035] Please refer to figure 1 As shown, the present invention provides an offline two-dimensional code payment method, comprising the following steps:

[0036] S10), the payer displays the payment QR code: the payment QR code information must contain signed identity information and payment information. The signature is an encryption method, which can ensure security through encryption. Not any collection device can scan it to deduct the payment, but only those who have the corresponding decryption method can deduct the payment.

[0037] S11), scanning the payment QR code: the payment receiving device scans the payment QR code provided by the payer;

[0038] S12), signature verification: after the payment receiving device scans the payment QR code, it parses the information corresponding to the Q...

Abstract

The invention provides an off-line two-dimensional code payment method and system. The method comprises: a payer displays a payment two-dimensional code including signature and payment information; a payee device scans the payment two-dimensional cod; the payee device verifies the signature information; if the verification is done successfully, the payment two-dimensional code is stored; whether the payee device is in a networking state is determined; and if so, the corresponding money deducting operation is carried out based on the payment information. With the method, secure off-line payment can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code payment, in particular to an offline two-dimensional code payment method and system thereof. Background technique [0002] With people's pursuit of convenience, two-dimensional codes are widely used in daily life, such as commodity information identification; Simple QR code payment has emerged; however, at present, all processes of QR code payment require network support, including QR code production process, code scanning process and deduction process. This has led to a great dependence of QR code payment on the network. In places with poor signal, the payment efficiency is greatly reduced, and the communication speed of the network determines the payment response speed, which limits the use of QR code payment in payment. It is used in occasions with high requirements on response speed. Contents of the invention [0003] The purpose of the present invention is to solve the proble...
