Abstract: Transaction processing method, apparatus, device, medium and system are disclosed in the embodiments of the present application. The method includes: acquiring biometric characteristic information of a user; transmitting the biometric characteristic information to a target biometric information server, so that the target biometric information server determines card information of the user according to the biometric characteristic information for feedback; receiving the card information of the user fed back by the target biometric information server; transmitting a transaction request to an authorization server corresponding to the card information, so that the authorization server performs authorization verification on a transaction corresponding to the transaction request; receiving a transaction authorization verification result fed back by the authorization server; and performing the transaction according to the transaction authorization verification result.

Abstract: A computer processing system for implementing data upgrade includes a communication interface device, at least two application servers and a database server for storing data, wherein the communication interface device detects in real-time a connection state of the communication interface device and each of the application servers, and sends data received from external to an application server connected with itself for processing; all the application servers are connected with the database server to process data and store the processed data in the database server, the data upgrade is implemented in batch for the application servers requiring the data upgrade by disconnecting the application servers from the communication interface device and reestablishing the connection of the application servers with the communication interface device after the data upgrade is completed. During the data upgrade, upgrade may be implemented without shut-down of the system.
