We use Square Stand and Square POS for our bar. Customers open tabs with credit cards and they add to them throughout their stay as they buy more drinks or food, then close out as they leave. On busy event nights, we want to add a second hand-held ipad with a plug-in Square reader that our barback can use to close out credit card customers while the other register is busy. But I need to know if there's a way to have the open tabs synced so that they show up on both tablets signed into Square, before spending more money on this if there's no way to make it work. I have NOT been able to figure out how to do this using my iphone as a second device - am I missing something?
