Offline point of sale is a vital part in any retail store environment. Is it important to you that the doors of your store stay open even when you are experiencing connectivity issues to your back office database? To revert to manual invoice books can be painful and time consuming, not to mention testing your customers’ patience.
The software should be developed to address the online vs offline shortfall. Whilst online, your terminal updates all transactions to the back office database immediately. When there is a break in communication to the back office database (offline mode), the terminal should store all transactions locally. As soon as the connectivity has been restored, these transactions must synchronize to the back office database seamlessly.
