        $buffer = explode("\r\n",$buffer);
        $result = []; 
        for($a=1;$a<count($buffer);$a++){
            $data = Parse_Data($buffer[$a],"<Row>","</Row>");
            $PIN = Parse_Data($data,"<PIN>","</PIN>");
            $DateTime = Parse_Data($data,"<DateTime>","</DateTime>");
            $Verified = Parse_Data($data,"<Verified>","</Verified>");
            $Status = Parse_Data($data,"<Status>","</Status>");
            $ins = array(
                    "pin"       =>  $PIN,
