Recently, there are rumors on the Internet that it is possible to open a locker with a barcode photo taken with a mobile phone. Yesterday, the reporter conducted experiments in three large supermarkets in the urban area and proved that this method is indeed feasible. Supermarket staff reminded that for the safety of their belongings, they should still keep the receipts properly.
Yesterday afternoon, the reporter came to a supermarket on Dongyue Road. In front of its lockers, many citizens are storing things. When the reporter asked them if they had tried to open the door with a barcode photographed on a mobile phone, they all shook their heads.
Subsequently, the reporter pressed the storage button, and a bar code receipt slowly "spit out". After getting the receipt, the door of the locker was closed. The reporter took out the phone, laid the receipt flat, pressed the shutter button at the barcode above.
The reporter brought the barcode photo on the mobile phone close to the scanning port, and the door of the locker slammed open. The sensitivity was almost the same as the paper barcode. In order to prove whether each locker can be opened by this method, the reporter repeated the trial three times, and the locker door could be easily opened.
It is worth noting that the mobile phone should be horizontal screen, the size of the photo barcode is similar to the real thing, and it is easier to open the box.
But not every locker can use this method. The reporter has repeatedly experimented in several supermarkets and found that newer lockers are very convenient to use this method, and some old lockers are more difficult to identify. In addition, if the barcode is not very clear when shooting, it will be a little slower, but it can be opened.
The reporter visited many supermarkets and learned that almost every day, many customers asked the supermarket staff to help open the cabinet door because of the loss of barcode paper. The staff said that if the customer can remember which cabinet is OK, it will be more troublesome if it is not remembered.
During the experiment, many citizens also gathered to watch. They all expressed their surprised expressions and sighed, "It's amazing!" Many citizens showed different attitudes after learning about the situation.
"In the future, when the paper slips off, you can open the cabinet for convenience." Huang Shaomin sighed. There are a few citizens who share her views, and most of them are young people. Some citizens also expressed concern: "Although it is convenient, if it is used by bad people, it will be bad." Ms. Chen said that since the barcode can be retrieved by the mobile phone, it will take more care when storing items in the future.
"Cash, gold and silver jewellery, marketable securities, certificates and other valuable items will not be stored in this mall." Supermarket staff reminded the public to keep the password strip in order to avoid being photographed by someone to open the locker and remove the items.
With the improvement of people's quality of life, people's lifestyles have also become varied. Different kinds of recreational products are starting to appear in people's lives, such as electronic cigarettes. The emergence of e-cigarettes represents a part of young people's thinking and means that electronic products are beginning to show a trend towards diversity.
