How to connect Square to Acuity Scheduling

[Mjribic]

I have the cup reader to connect with my acuity, but I alway have trouble with it disconnecting and connecting. Do you know if a square mini terminal would work better where it's always connected?

The mini terminal is a stand-alone device. It does not connect to the app or anything else. 

It’s useless to connect to acuity.
