Multi-Threading and Shared-Memory Pool Techniques for Authorization of Credit Card Systems Using Java

This paper presents a framework and solution for improving the efficiency of the authorization processing of credit card transactions using multi-threading and shared-memory pool techniques. Through the use of both techniques, a prototype of a real-time multi-threaded authorization system has been developed with Java platforms to overcome the slow sequential authorization processing of a single-threaded model of current credit card authorization systems. Via multi-threading technique, it allows parallel execution of the validation functional units involved during the authorization process of credit card transaction through multiple threads. It also enables a separate thread to be executed in the background of the process to perform data synchronization maintained in the shared-memory pool with the main system database
