But do you know it can unlock? Of course, it is not to open the lock of your door, but to open the bag storage cabinet in the supermarket. Take a paper bar code with your mobile phone and open the bag storage cabinet with the photos in your mobile phone.

Like many people, Xiao Bian felt a little strange at that time, because he would never think of the connection between the mobile phone and the barcode and the locker when using a mobile phone, but the fate was so magical that the three really found the intersection. The members of the studio tried it in person and succeeded. Adhering to Love to play computer games It has always been the spirit of loving practice and struggling, so Love to play computer games The members of the studio went to the supermarket to do the video measurement again:

As you can see from the video, just use Mobile phone shooting The photos come out clearly enough, and then adjust the size proportion of the photos to be consistent with the paper bar code, so that the door of the bag storage cabinet can be opened smoothly, and it is successful. In fact, it is not unusual to open the storage cabinet by taking pictures with a mobile phone, because the scanning principle of the storage cabinet is to form different reflected light signals to read and open the cabinet door according to the black and white size of the barcode and the spacing between the barcodes. Of course, even photos of the barcode can open the cabinet door.

But I remind you here that it is good to shoot barcodes with mobile phones, which saves the trouble of saving paper barcodes. But after shooting, don't throw the paper bar code around. It will be troublesome if it is picked up by malicious people.
