Guys, I have an app, which offers discounts whenever a customer uses my app in a store. It is the weekend so I want answers before I speak to my app development teams come tomorrow. I would like to record: * Total Spend * Customer Number * Time & Date of transaction * Venue Which software would you use to collate the information and would you have to set up a separate server for the information to be then sent to me to access remotely? I am thinking of having a QR code which a user scans, the information is then encrypted and sent to a hard drive which is connected to the internet wirelessly, this is then forwarded onto me so I receive live updates... I will also set up emergency alerts of when signal is lost. Has anyone ever used something like this in their business? Let me know how it went.
