The POS applications can be either as online or offline model. The POS online application requires moderate or high rate data connectivity to provide the services for the users. However, when the POS terminal sends a request to centralized corporate database over online model, it takes some time to complete the transactions due to the connectivity and network problems. While carrying the data through online, if any connectivity problems occurred, it leads to high risks for the users as well as for the organizations. Hence, the POS applications deployed by a single or multiple organizations need to support availability, scalability and privacy at high-level.
