The mobile phone can also open the barcode locker. Did you know this ? The barcode locker can also be opened with a mobile phone. Did you know this? I believe that many people now know that this statement has already been madly passed out. Is this statement really true? Xiao Bian took everyone together to verify.
If the barcode locker phone can really open, is it not insecure? It is well known that mobile phones can make calls, go online, and shop, but do you know that the phone can be unlocked? Recently, some netizens sent microblogs saying that after depositing things in supermarkets and taking vouchers, they used a mobile phone to take a picture of the bar code. When they took things, they scanned the bar code photographed by the mobile phone, and the locker could still be opened. is this real?
A reporter specifically tried to verify it. After one slipped out, the reporter took the receipt and took the barcode with his mobile phone, but he took the photo on the mobile phone at the scanning port and brushed it up and down several times. The doors of the cabinet are "indifferent". Later, the reporter went to another big supermarket to experiment again and the door still could not be opened. Suspected the problem is the sharpness of the shooting photos, the reporter changed the camera to take pictures and then brush, still can not open the door. At 5 o'clock in the afternoon, the reporter went to a third supermarket to use another mobile phone to take pictures and change the shooting method: take the slips on the table and adjust the proportions of the pictures to match the slips. The captured photographs were directed at the locker scanning port and the door opened with a click. Several cabinets were tested and all were opened. It is not unusual for mobile phones to take photos to open the locker. The scanning principle of the cabinet is based on the black and white size of the bar code and the different spacing between the bar codes to form different reflected light signals for reading.
What were the reasons for the failure of the reporter twice before? The staff explained that whether the door could be opened or closed was not affected by the camera. As long as the bar code ratio could be opened, the sensitivity of the scanning of the door and the locker, the flatness and clarity of the slip, and the phone could not be opened after the camera. The screen material, even the film, reflective different factors.
Can a mobile phone shoot a barcode to open a bar code locker door and it will not bring security risks? Bar code locker even if it can be opened by mobile phone, but bar code paper in his own hand is difficult and there are people in broad daylight to snatch bar code paper not? Therefore, it does not cause any security risks. We only need to bear in mind that it is most appropriate to keep the barcode paper properly when storing good items in your own bag, so that you do not have to worry about the locker being opened by others.
