Abstract: A method is disclosed that includes: obtaining two-dimensional code of a to-be-generated two-dimensional code image; performing error resilient coding by using a coding algorithm with a predetermined error-tolerant rate, to obtain error-tolerant-processed two-dimensional code; determining a code element shape that is corresponding to each data information bit in the error-tolerant-processed two-dimensional code and that is in a generation region of the two-dimensional code image; determining, according to a predetermined arrangement rule of the two-dimensional code, first position information that is corresponding to each data information bit of the error-tolerant-processed two-dimensional code and that is in the generation region; determining second position information of each positioning point bit in the generation region; and generating the two-dimensional code image based on the first position information, the code element shape corresponding to each data information bit, and the second position informat

Abstract: This specification discloses offline payment methods, devices, and systems. In an implementation, a method includes: collecting a payment code of a payer's terminal device, transmitting a target optical signal within a predetermined range, wherein the target optical signal is generated based on transaction information, and the transaction information comprises at least a transaction amount and a collection account, determining that the terminal device is turned back online from an offline state, and sending collection information to a payment server. The collection information comprises the transaction information and the payment account, wherein the payer's terminal device is configured to: collect the target optical signal and identify the transaction information when the payer's terminal device is within the predetermined range, and send payment information to the payment server, wherein the payment information comprises the transaction information and the payment account.

Abstract: This specification discloses methods, apparatus, devices, and systems for sending payment pages based on aggregation codes. In one implementation, a method includes: receiving code information obtained by the terminal device from scanning an aggregation code, obtaining a standard payment page corresponding to the code information, where the standard payment page comprises page information generated by the first server based on a historical payment page, and where the historical payment page is provided by a second server for the target aggregation code, and sending the standard payment page to the terminal device.

Abstract: Implementations of this specification disclose payment computer-implemented methods, computer-implemented systems, and non-transitory, computer-readable media. A computer-implemented method includes a payment instruction sent by a first user by scanning an order QR code is received, where the order QR code is generated based on a first order corresponding to a target product, and the first order is generated based on a purchase operation performed by a second user for the target product. The first order is set to an occupied state, where a payment instruction of a user other than the first user is rejected to be executed when the first order is in the occupied state. A second order of the first user is created based on an order identifier of the first order in the occupied state. A payment operation is performed based on the second order.

Abstract: Embodiments of the present application relate to a method for recognizing information, a system for recognizing information, and a computer program product for recognizing information. A method for recognizing information is provided. The method includes locating a card zone for each frame within a card image frame sequence comprising a plurality of frames, locating an information zone within each card zone, dividing each information zone into at least one character zone, de-blurring a character zone corresponding to a same region across all the frames in the card image frame sequence, and recognizing character string information based on the de-blurred character zone.
