Many people when going abroad often prepare a small paper tag attached to the suitcase with the name, age, address, and contact phone number of the owner, to avoid confusion or if there is confusion, it will be returned easily. But the disadvantage of this method is that the owner's personal information can be revealed and cause the owner unnecessary trouble.

According to a foreign media report, criminals can pay attention to the information on checked baggage, secretly put prohibited items next to your suitcase and write the owner's name as the name on the luggage, they know the home address and personal information of the suitcase owner, if successful, they can go and get it later.

Recently, Brazilian police arrested a group of drug smugglers who copied passenger information and pasted it on their own suitcases. In addition to other items in the suitcases, they also put drugs and transported them by air.

Another incident was in 2010, a 50-year-old woman from Hong Kong named Lam Tran Dinh went to Malaysia to visit relatives. When going through customs, she helped an old lady carry her luggage through customs and was detained, checked and discovered in the old lady's luggage bag that she asked her to carry, there was 1.8 kg of drugs. Malaysia is a country that applies the death penalty for drug trafficking and transportation of 15 grams or more, so Lam Tran Dinh was sentenced to death.
