I am trying to find a solution to get the client's iPad unique MAC/Wifi address. I found some solutions here but it gets the MAC address of the server, but I want the client's address. Thanks.
It is not possible to retrieve the clients MAC address, the MAC address is determined by the clients hardware and due to many restrictions your web application tipically can´t get it. I tried various workarrounds using javascript a long time ago without any success.
