I assume you're doing this on the server. You don't say what technology
you're using, so I'll try VBScript (ASP).
Function HideNumber(sNumber)
Dim iLength
Dim sNewNumber
Dim i
sNumber = Replace(sNumber, " ", "")
iLength = Len(sNumber)
For i = 1 To (iLength - 4)
sNewNumber = sNewNumber & "*"
Next
sNewNumber = sNewNumber & Mid(sNumber, iLength - 3)
HideNumber = sNewNumber
End Function

Should be fine on the server, I wouldn't recommend sending the credit
card number down the pipe and then manipulating it with JavaScript on
the client.
