Systems and methods for cloud-based asynchronous communication

Abstract

A method for cloud-based asynchronous communication includes receiving a transaction request message from a cloud-based application, sending the received transaction request message to a PIN pad by way of an electronic message repository, updating a current state according to the received transaction request, listening for a new incoming message event from the electronic message repository, receiving a new incoming message event from the electronic message repository, and retrieving an incoming message from the electronic message repository, determining whether the retrieved incoming message matches the current state, upon determining that the retrieved incoming message matches the current state, transmitting the retrieved incoming message to the cloud-based application, and upon determining that the retrieved incoming message does not match the current state, retaining the retrieved incoming message in the electronic message repository.
