Offline payment method

Abstract

The invention relates to the field of payment methods, and particularly discloses an offline payment method, which comprises the following steps of: pairing a mobile terminal with a service machine, selecting a service function and paying; after payment succeeds, enabling the mobile terminal to send the pairing information, the payment information and the selected service function to a backgroundserver, and enabling the background server to generate a verification signal and sends the verification signal to the mobile terminal; enabling the mobile terminal to send the verification signal to the service machine; and enabling the service machine to start to operate when the check signal is matched. By the adoption of the method, offline payment can be achieved through direct interaction between the mobile terminal and the background server and non-network-signal interaction between the mobile terminal and the washing machine, it is guaranteed that a user normally uses the washing machine, use of the user is not delayed due to the fact that the washing machine cannot interact with the background server, and the user satisfaction degree is improved.

Description

technical field [0001] The invention relates to the field of payment methods, in particular to an offline payment method. Background technique [0002] Existing service machines such as commercial washing machines, commercial drying machines, etc., adopt the following payment methods. One is to use online payment. However, in order to avoid occupying space, such washing machines are usually placed in remote corners, which will cause The signal strength is poor, so that the normal communication between the washing machine and the background server cannot be guaranteed, which seriously affects the payment function of the washing machine, and thus affects the use of users; the second is to use cash payment, but the cash payment requires staff to be on duty at all times to facilitate timely charging. The user uses it in time, which wastes manpower and financial resources; the third is to use coin-operated payment, which requires the user to bring cash, and needs to put change in...
