it can be understood that the docking permission may be protocol docking of wireless data signals such as bluetooth connection, and after the payment device receives the docking permission, the payment device and the merchant cash register are wirelessly docked.
S300, constructing a local database, wherein the local database is used for storing the pictures and the corresponding ID accounts;
a local database is built within the payment device for storing facial pictures of the customer.
To illustrate the intent of this application at this step, a local database is provided in the payment device, which can only store facial images of a certain memory capacity, and the existing storage media, typically 8G, 16G, 32G, 64G, · · · 512G memory, are installed in the payment device for recording the facial images of the customer; in another embodiment, in order to clean the memory in time, when a face image in the local database is not verified for a preset time (verification is that the payment device acquires the face image of the customer, and the ID account corresponding to the face image is verified from the local database), the face image is deleted, and the preset time is preferably one year.
In essence, in the process of selling commodities by merchants, the merchants are regional, the local database can store facial pictures of regular customers, in the process of selling commodities, the payment equipment compares the acquired facial pictures of the customers with the corresponding facial pictures stored in the local database to determine ID accounts, and when the facial pictures are consistent, money is directly deducted without inputting passwords by the customers.
S410, when the Internet connection of the payment equipment is unstable, activating a local database, acquiring a facial picture of a customer, judging whether the facial picture is stored in the local database, and if so, directly deducting money from an ID account corresponding to the facial picture; if not, acquiring a facial picture of the customer through a preset four-dimensional model and inputting the facial picture into a local database, then acquiring an ID account of the customer, which is input by a merchant cashier desk, and completing deduction after the customer inputs a password corresponding to the ID account for the first time;
s420, when the Internet connection of the payment equipment is stable, activating an Internet database and a local database, acquiring a facial picture of a customer, judging whether the facial picture is stored in the local database, and if so, directly deducting money from an ID account corresponding to the facial picture; if not, acquiring a facial picture of the customer through a preset four-dimensional model, inputting the facial picture into a local database, calling an ID account corresponding to the facial picture from an Internet database, and completing money deduction after the customer inputs a password corresponding to the ID account for the first time.
