2results about How to "Improve payment efficiency" patented technology

The application provides a face payment method and device, equipment and storage medium, and relates to the technical field of computers. The method is applied to a payment terminal, and the method comprises the following steps: collecting a face image of a user; sending a first payment request of a current order to a payment server, wherein the payment request comprises the face image; receiving a first display instruction sent by the payment server, wherein the first display instruction is used for instructing to display selection controls of at least one prepayment order, and the at least one prepayment order is an order associated with identity information of the user; and in response to the first display instruction, displaying the selection controls of the at least one prepayment order, wherein the selection controls are used for the user to select a first order in the at least one prepayment order, and the first order is an order for which payment is combined with the current order. The method can not only improve the payment efficiency of the at least one prepayment order associated with the identity information of the user, but also improve the user experience.

The application provides a circuit module of a payment terminal, comprising a substrate, a UWB chip, an NFC chip, an SE chip and a processor; the UWB chip is arranged in the substrate and is used for UWB payment; the NFC chip is arranged in the substrate and is used for NFC payment; the SE chip is arranged in the substrate, and the SE chip is provided with a key storage used for storing a payment key and a key calculation algorithm; the processor is arranged in the substrate, the UWB chip, the NFC chip and the SE chip are connected with the processor, the processor is connected with a Bluetooth antenna, the processor transmits a wake-up signal through the Bluetooth antenna to wake up a UWB tag in a range; UWB non-inductive payment and NFC card swiping payment can be supported, and multiple payment modes can be selected; the payment efficiency can be improved through Bluetooth wake-up; the transmission data is subjected to encryption processing, the safety of payment information and transaction data is ensured, and the safety of the payment process is significantly improved.
