This is pretty interesting! What hardware are you using for vendors? Kinda curious how you deal with the network aspect of it. Sometimes venues have low cell reception or flaky venue networks.
Vendors just use their own smartphones and use our app to scan customer’s QR code to charge them.
As for the network we rely completely on the cellular network. We use an extremely small amount of data (a tiny fraction of what an image a user might be posting to FB/IG/SC/etc would be) so unless the networks are completely down we can manage without issue.
We check out venues/grounds/etc for cellular reception/speed ahead of time to make sure we are a good fit for a festival to try and avoid internet connection issues.
