Hi Adrienne, We primarily use NSCAN in our own buildings, but we do host some off-site events every year that we ticket and need to scan people in at. All you need is the IP address of the venue and the wifi login info -- you'll need to get the IP address white listed with RAMP (if you are hosted) and then you'll be all set. As long as we can get on the wifi with the scanners we haven't had any issues.
