Hi everybody, I am new to this board. I have a new client that has a public access point for his business. He wants to ensure each person that uses this access point registers so he can get everyone's contact information to send them out coupons, etc.

The way I am seeing it is everytime a computer connects to the access point, the mac address is tested against a database. If the mac address does not exist, the user must register the computer. My question is, what type of mechanism should I use to automate this process?

Example scenario:
I connect to this network. I open firefox. My homepage is google.com but since this mac addr is not registered, I am redirected to a registration page.

Thanks in advance for suggestions
