he provincial government said Friday it would legislate to manage casinos to improve transparency.
This will be an upgraded version of the government's ordinance for the casino industry, which was launched last June.
Under the new legislation, which will be effective from January, casinos must establish a permit system for people to enter any restricted areas — the storage room of gaming devices and computer rooms — in their buildings.
The casinos should also increase the number of security cameras to reduce blind areas, and build game facilities based on the new rules.
The government has also banned the casinos from using illegal gaming equipment.
To improve transparency, Jeju Island also requires gambling companies to calculate their daily income immediately, sell poker chips at the gaming table, install electronic game tables, and provide serial numbers for each game contract.
The government also requires casinos to record information of their foreign customers including their name, nationality, date of visit, passport number and passport expiration date.
The casinos must also store the identification of Korean visitors who are especially allowed to enter foreigner-only casinos.
Jeju Province decided to intensify its regulations after a series of crimes related to the casinos.
In 2014, Chinese police caught about 100 Chinese illegally gambling at casinos on Jeju Island.
In the same year, Korean police arrested five casino employees on suspicion of embezzling about 5 billion won ($4.3 million). Two men were arrested for using casinos to transfer 63 billion won from China to Korea.
This year, a Chinese man was arrested for killing a Chinese woman on Jeju Island and spending all her money at a casino after the murder.
