The government on Friday announced measures to stop quarantine hotel room scalping, saying hotels should verify guests' real names and that they should pay in full when booking a room.
In a statement, the administration said it had decided to implement the measures with immediate effect after talks with the hotel sector.
It added that hotels shouldn't let travel agents block-book the rooms without supplying guest details.
Agents should also be required to list the breakdown of fees on customers receipts, and hotels should ensure agents charge the same rate as listed on the government website, the administration said.
The government said it will not tolerate any kind of scalping activities and will take appropriate follow-up actions if instances of non-compliance are found.
Meanwhile, it said three more hotels will take part in its quarantine hotel scheme from August to October, providing some 900 additional rooms.
A total of 24,000 rooms in 65 quarantine hotels will be available for inbound travellers to undergo quarantine during the three months.
