The embodiment of the invention discloses DOI (Digital Object Identifier)-based payment method, device and equipment. In the scenario where code scanning payment is carried out through a code scanningdevice by a user, the amount that the user needs to pay can be displayed by a pricing device; a payment two-dimensional code can be provided to the user on the basis of the displayed amount by a corresponding settlement device; the payment two-dimensional code reflects the amount that the user needs to pay; and therefore, the user only needs to scan the DOI of the amount by using the code scanning device and the payment can be completed.

DOI (Digital Object Identifier)-based payment method, device and equipment

The embodiment of the invention discloses a payment device, system and method based on Bluetooth broadcasting. The payment device includes: a Bluetooth module for broadcasting a transition characteristic code; a keyboard for receiving a user-initiated input transaction amount; a display screen for display; a wired/wireless network interface for accessing the network; a clock unit; a storage module; and a processing unit. The processing unit is electrically connected with the Bluetooth module, the keyboard, the display screen, the wired/wireless network interface, the clock unit and the storagemodule through a system bus. The processing unit generates a transaction characteristic code according to a preset logic according to the transaction amount and broadcasts the transaction characteristic code through the Bluetooth module. The embodiment of the invention solves the problems of slow payment speed and payment risk of stolen card by generating execution instruction between the paymentdevice and the mobile terminal according to the transaction instruction by the server, thereby ensuring the payment safety and improving the payment speed.

The embodiment of the invention discloses an information display method based on a customer displayer and the customer displayer. The customer displayer is provided with a display screen. The method comprises the steps that the advertisement information pushed by a background server is acquired and displayed on the display screen; a payment instruction is detected and then the cargo amount to be paid is acquired, and a payment interface is generated according to the cargo amount; and the payment interface and the advertisement information are displayed on the display screen together. The customer displayer can generate the payment interface according to the amount to be paid so as to facilitate payment for the user; besides, the advertisement information pushed by the background server canalso be synchronously displayed so that the advertisement cost can be reduced.

Implementations of the present specification provide product checkout methods and apparatuses, and electronic devices. The method includes the following: scanning, by a client, a product barcode to enter a shopping cart interface, where the shopping cart interface is used to display product information obtained through barcode scanning; sending, by the client, a checkout request to a server when obtaining a checkout instruction, where the checkout request carries the product information of a shopping cart; generating, by the server, a payment code based on the product information of the shopping cart when receiving the checkout request, and pushing the payment code to a checkout terminal; and displaying, by the checkout terminal, the received payment code, so that the client scans the payment code to complete payment.

Commodity settlement method and apparatus and electronic device

The invention discloses an intelligent cash registering method, device and equipment based on a two-dimensional code and a storage medium, and relates to the technical field of cash registering application. According to the technical scheme, the method comprises the following steps: acquiring payment information via a user interface, wherein the payment information at least comprises product information and required payment; generating a unique two-dimensional code, wherein the two-dimensional code codes the payment information; displaying the unique two-dimensional code and the payment information, the two-dimensional code is scanned by equipment of a payer; acquiring an online payment result of the equipment of the payer; and matching the payment result with the required payment, and outputting voice prompt of cash registering success if the payment account is consistent to the required payment. The intelligent cash registering method, device and equipment based on the two-dimensional code are used for registering cash through two-dimensional code payment directly, active payment result confirmation is carried out, and payment risks are avoided.
