Looking for Point of Sales extension for v2.1.0.2

I just upgraded my Opencart from v1.5.6 to 2.1.0.2 and found my Point of Sales extension no longer compatible so I am looking for a new one urgently. Can anyone give me some suggestion please?

Check out the one below, it even has an import function:
