lan - Registering a device with an application based on MAC address -


i trying build application runs on local server, can accessed smart phone devices connecting through router (say placed @ security gates). in-campus check-in/check-out local application, , not meant accessed clients on internet.

now want register each smartphone device uniquely web-application there no details fed in, or no login required each time during check-in or check-out. , approach register each device based on mac address.

will able retrieve mac address of device on network connected application? prefer php.

exec('arp '.$_server['remote_addr'],$user_mac);

will arp command able retrieve addresses on network? also, there better ways identify devices uniquely, , permanently?

thanks.

mac addresses not visible across segments, need have no routers between , client able mac address arp.
