March 17, 2020 Arrival health card is a joke
Many years ago when people went to the Mainland, they had to fill in a health form which did not require any proof of identification. I once heard of people who sometimes used false names, even names like Mickey Mouse and Ronald Regan.
Hong Kong's current arrival health card is in the same category. No proof of identification is required. False names, addresses and phone numbers can easily be used. A useless exercise.
Also pointless is the question "Have you been to (China, Iran, Italy etc) in the past two weeks?" No one need tell the truth. There is no checking of travel records.
Stopping the virus is a serious business, not a game. Hong Kong's current arrival card is a waste of time, money and personnel.
