EIGHT different sets of gambling chips worth hundreds of millions of dollars are being printed in France and rushed to Macau's casinos in a new strategy against robbers. Punters accustomed to using the same chip throughout the nine casinos in the Portuguese enclave will soon have to use one type for each gambling hall under the policy triggered by last week's record-breaking $38 million raid. The existing type will only be used in the Lisboa casino. The measures were revealed by casino bosses yesterday as authorities replayed a dramatic video-tape of a lone police officer firing a shot at the armed robbers during their getaway from the casino in the Hyatt Regency Hotel on Taipa. The tape, recorded by a camera near the entrance to the Diamond Room, shows the robbers crouching and carrying bags stuffed with chips and cash and armed with pistols and an AK-47. As they leave the entrance a police officer appears on his haunches from behind a bar and fires a shot. One of the robbers returns fire and almost $4 million in chips is spilled in the foyer of the casino, but nobody is hurt. Macau Security Police chief of operations Rui Teixeira de Freitas said yesterday crime groups in Macau were trying to pass off many of the stolen chips, but had been hampered by casino management's loss-control measures. The measures include forcing high rollers who hold $50,000 and $100,000 chips, which form the bulk of the stolen booty, to register their chips by tonight or face having them declared worthless. ''A better system would be one that does not use chips. That would be safer for residents and tourists and we are holding talks with casino management about this,'' Mr de Freitas said. ''For security reasons we must change some procedures. Our concern is for the safety of local people and tourists who visit Macau's casinos.'' Mr de Freitas said the video of the exchange of gunfire was being shown because many people did not believe the enclave's police had done enough to stop the robbers. A Macau casino executive said yesterday permission was being sought from the Gambling Inspections Department for the introduction of new sets of chips in denominations of $5,000, $10,000, $50,000 and $100,000.
