It is not there.

That would be a security violation and risk !

Shoot, that would work in tandem with ID verification.

Is this for an intranet-only site by chance?

You might try if it works in Visual Basic or C++
If you can do that you could try if with either a DLL or a clientside
ActiveX (but latter would only work in IE)
Maybe a JavaApplet could do it
But I am not sure if it would work, never tried it.

Internet, I am thinking of Age verification as well as ID'ing the person's
computer for purchases. Since MAC Addresses are unique they would be a good
identifier for someone that bought something at your site. Just one more
thing to add to the fingerprinting of PC's that hit my site.

You would need a signed applet or component which would ask the user's
permission to access the local system (browser would ask).

Your business would also drop to 0 the minute word got out that you were
doing this (ask Intel how many user's have the CPU serial number enabled on
their PIII systems).

If you want to keep track of users ask them to register and require a login
to get into your site.

I do but there is the possibility of people lying and in order to make a
best effort to prove that the person is who they are things have to happen
like this. People can expect to have to do a little more when payments are
involved and I don't something like giving up the Mac Address is that bad
especially since it would only be used to argue when people say that they
did not visit your website and didn't buy anything.

Comes down to fraud protection.

Even then it does not work. My DraytecVigor router can be set to any MAC
address I want, since my cable connection does not need it.

MAC addresses are NOT that unique !!!

2

Needing something for a supposed(!) legal use does not mean the ideea of
internet safety should be compromised.

It is like asking someone's housekeys by a bank to have a look if he is
really living there on opening a bank account.

I don't think this will help your security needs BUT here is a function I
have used a few times to pull mac address
<%
function GetMACAddress(strIP)
Set net = Server.CreateObject("wscript.network")
Set sh = Server.CreateObject("wscript.shell")
sh.run "%comspec% /c nbtstat -A " & strIP & " > c:\" & strIP &
".txt",0,true
Set sh = nothing
Set fso = createobject("scripting.filesystemobject")
Set ts = fso.opentextfile("c:\" & strIP & ".txt")
macaddress = null
Do While Not ts.AtEndOfStream
data = ucase(trim(ts.readline))
if instr(data,"MAC ADDRESS") Then
macaddress = trim(split(data,"=")(1))
Exit Do
End if
loop
ts.close
Set ts = nothing
fso.deletefile "c:\" & strIP & ".txt"
Set fso = nothing
GetMACAddress = macaddress
End function

strMac = GetMACAddress(strIP)
%>

<input type="text" name="MacADDY" value=<%Response.Write(strMac &
vbcrlf)%>/>

If you permit me to modify this a bit...

function GetMACAddress(strIP)
GetMacAddress = ""
Set net = Server.CreateObject("wscript.network")
Set sh = Server.CreateObject("wscript.shell")
sh.run "%comspec% /c nbtstat -A " & strIP & "|find ""MAC Address"">c:\"
& strIP & ".txt",0,true
Set sh = nothing
Set fso = createobject("scripting.filesystemobject")
fileContents = Trim(fso.opentextfile("c:\" & strIP & ".txt").ReadLine)
fso.deletefile "c:\" & strIP & ".txt"
Set fso = nothing
GetMacAddress = Replace(fileContents, "MAC Address = ", "")
End function
