Hotspot server

Hey I want to start a hotspot server for my hotel and I want to collect data of my guest for security purpose like name, phone number and mac address and get those data on my sheet and can anyone help to to make it

Why would you need to collect your guest’s MAC address, phone and name for security purposes ?? Doesn’t your hotel requires some kind of ID at check in ?

I hope your hotel is not in Europe because I’m sure you will be violating some kind of GDPR…
