MAC address of your clients, or the machine you're running on?
If you're talking about clients, then that's impossible unless they're
running on the same local network as the server (i.e. connected to the
same router, in which case you can use command-line "arp -a xx.xx.xx.xx"
in Win, or some equivalent in *nix).

Re: Detect MAC address with PHP
Thanks for the very quick reply, I want to know the mac address of my
clients as I guess these is the best way to fight with internet fraud.
Too sad according your answer seems no way to detect the remote mac
address... as you know to detect the ip address is not very useful... so is
there some better way to detect the fraud? my website has lost 2000 dollars
as some guy are using stolen credit card and do repeat order from different
ip address and different account...

Unless you have some way of identifying stolen credit card numbers, how
do you expect to be able to protect against this? How would knowing MAC
addresses help?

Yes, but except on wireless networks, it's usually not worth the
effort to try and fake one, because the mac address is only seen
by the local network. Even on wireless networks it only applies
to setups that have tried to lock access to a list of authorized
clients, and those systems probably are using WEP or WPA also.
Faking a MAC address can be as easy as (on FreeBSD):
ifconfig fxp0 ether 01:23:45:67:89: ab
It's also easy on Linux (but the syntax may vary a bit), and Windows
XP has a GUI blank to fill in to change it. The UNIX commands
aren't permanent: you have to run them on each boot, so you stick
them in a startup command script. The XP GUI arranges that the
setup is changed every boot.

Your best bet is to use a processing company that will offer you some form
of seller protection, so that when a stolen card is used, the processing
company or the credit card company (not you) will refund the victim. If you
can't find such a company, you may want to purchase fraud or theft
insurance, which will compensate you for stolen amounts.
Good luck,

Does any payment processing company offer such protection? It must be
amazingly expensive, surely?

Why it would be the best way ?
The MAC address of the networking card cna be changd on many
network adapter cards.

Re: Detect MAC address with PHP
You should also consider GeoIP to check the Country of the CC matches the
location where the details are being submitted from.

I see the logic, but this could stop legitimate transactions. For instance
when I visit a hotel in Switzerland I pay for internet access using my UK
credit card...
