Below is a video demonstration of TCS POS for NetSuite. Also works with JCurve.
TCS POS for NetSuite works real-time with NetSuite and does not require any NetSuite user licences. The Point of Sale speed of processing is fast and the user interface calls data directly from NetSuite, so there is no syncing of data. The interface can be configured to your requirements. It works off the NetSuite platform, so you get guaranteed uptime of 99.5%. http://www.netsuite.com.au/portal/au/platform.shtml
