Network redundancy is important more than ever and not only for data but operations as well. Certain point of sale systems can cease function if the network or the central server become disconnected, transactions cannot be processed, prices cannot be changed and so forth. Furthermore without data redundancy, one single failure can destroy all the data for the business. This is why we have built in an incredible amount of redundancy in our networking stack. If the network or serve go down, Polar POS will still be able to function, process transactions and perform all other operations just normally and connections are restored it will automatically resync.
