More and more people are using luggage with password locks. Many people think that having a luggage password lock means their belongings are very safe, and they simply stuff anything valuable or not into it. This is a big mistake, people often overlook the security vulnerability of zippers. With just a ballpoint pen, you can open the zipper of a suitcase, and even after stealing property, the zipper can be restored to its original state. The reporter used a ballpoint pen to test the three most common types of zippers: plastic, resin, and metal. The material of plastic zippers is relatively light. When a ballpoint pen is used to poke a certain part of the zipper, it will immediately open a small opening. Then, with a gentle flick to the side, the zipper will instantly "fall apart". After pulling the lock back and forth a few times, the zipper returned to its original state, with no visible signs of being opened.
Although many bags and suitcases come with password locks, facing the security vulnerability of zippers, all password locks are virtually non-existent.
The editor reminds everyone here that valuable items should be carried with you and luggage should not be out of sight.
