Flight Crew Took Evasive Action
Airport
As I was turning into the gate; with marshallers present; a Company baggage truck and one cart drove underneath the nose of the aircraft; probably less than 10 feet from contact.  If the First Officer had not told me to stop we would have hit him.  It was the most blatant unsafe ground equipment driving I have seen in 29 years.  Airport OPS person met us and told me it would be 'very difficult' to track down the driver.  He should not be working on an airport. Unsafe operation of ground equipment. Find him and fire him.
Air carrier Captain reported a baggage cart drove under the nose of the aircraft while being marshaled in; resulted in immediate braking.
