Implementations of the present disclosure provide a service processing method, device, and system associated with unified resource locator (URL)-based two-dimensional (code). In an implementation, a URL is received from a first service institution. The URL is obtained by a mobile device from scanning a 2D code provided by a service provider and sent to the first service institution. The URL is then parsed to identify one or more data elements including a service network identifier, a service institution identifier, and a payload including a service object identifier. The one or more data elements is sent to the second service institution based on the service institution identifier. Service information associated with the service object is received from the second service institution based on the service object identifier, and the service information is sent to the first service institution for presenting on the mobile device.
