Even you are running a small, medium, or large-sized business, the cloud-based system is really very helpful because it is:

– Cost-saving: no need to hire a professional IT to solve your issues – a store owner just need to upgrade the system monthly or annually with a minimal upfront cost. (The monthly fee often varies from $80 and $200/month).

– Highly Secured: Cloud-based server never stores sensitive credit card information in a back room. Instead, the data is always encrypted and sent over to a separate secure network. Therefore, your customers are not at risk of being invaded by important information. Better still, devices that integrate with the cloud-based system will be monitored constantly, detecting suspicious activity or rogue accessing.

– Online – Offline: if your system can be connected to the wifi, then that is great. But if not, then don’t worry. The systems will be synced in real-time once you’re back online.

    This is a good overview of what point of sale is and how to bolster your business by using it. Whenever I see “cloud” mentioned, I get concerned about security. I know there are some great security safeguards, but how often do they update them and how can a business keep up on what the latest security safeguards are for their POS?

    • You’re right. One drawback about the “cloud” is security, although it does have many benefits.
      Not bragging but it turns out to be a plus point for native solutions like ours to businesses using Magento. When data is synced straight to the Magento backend, the chance of data loss is minimized. 😀
