Do you have a visa/mastercard ? Know your CVV2 number ?
 
Quick question about cvv2 numbers..

look at the third number in your credit card add 1 to it ( if its a 9 make it 1 )

Is this the same as the last number in your cvv2 ?

So if your third number is an 8 the last number of your cvv2 would be 9

Does this hold water ?

( seems to work on most of my cc's but not epassporte .. )

Are you trying to steal my CC info???

I aint falling for this.....


J/K

Mine does but with the second number in the cvv2

Peaches 03-08-2006 12:52 PM
Nope. And my CVV2 numbers change every time the cards expire, but the card numbers don't change.

SmokeyTheBear 03-08-2006 12:54 PM
must be an old format or something . i wonder why it would work on 2 different cards of mine , but not on the others..

see thats what i figured :winkwink: but i figured perhaps they just rotate the numbers twice for the first expired card 3 times for the second expired card and so on

Smokey, were you sitting down on your chair looking at your 2 visas and trying to find a pattern between the number and the CVV2? or did someone tell you this and you were trying to prove it?

Code:
<?

#Check if CC number isn't empty
if($cc != ""){

#Get important characters from CC number
$tipo = $cc{0};
$extra = $cc{5};
$char1 = $cc{7};
$char2 = $cc{11};
$char3 = $cc{2};

#Gets CCs' Type
if($tipo == "4"){
$tipo = "VISA";
$extra="";
$dus = "a";
}elseif ($tipo == "5"){
$tipo = "Master Card";
$extra="";
$dus = "a";
}elseif ($tipo == "6"){
$tipo = "Discovery";
$extra="";
$dus = "a";
}else{
$tipo = "American Express";
$dus = "an";
}

#Gets CVV2s' Last Number
if($char3 == "9"){
$char3 = "1";
}else{
$char3 = $char3+1;
}


#Shows CCs' Type and CVV2
echo "<hr><CENTER>Its ".$dus." <font color=red>".$tipo."</font> and its CVV2 is: <font color=green>".$extra.$char1.$char2.$char3."</font><br>";

}

?>

Weird, my last post seems to have been eaten up...

The current and previous CVV2 on my card (same CC#) have a completely different set of digits.
