Toilet paper in public toilets is often stolen. How can we prevent this from happening?

Nowadays, there are many uncles and aunts who have nothing to do at home, so they often go to many public toilets to get toilet paper for home use. This approach is obviously very selfish. To deal with such selfish people, we must take very serious measures to stop them.

Swipe your face to get the paper. Nowadays, technology is becoming more and more advanced. If you want to prevent this situation from happening continuously, you can use technology to sanction these people. A machine that scans faces and takes out paper can be installed in every public toilet. This machine will give them paper based on facial recognition. This machine can only give out a little paper at a time, which is enough for many convenient people. But for those uncles and aunts who keep coming to get paper, it will be a waste of their time. This machine can only allow the same person to continue to pick up paper every ten minutes, and the amount of paper taken each time is also very small. If these uncles and aunts want to take a roll of paper home, they may have to swipe their faces there for a day. When the machine recognizes it a certain number of times, it will no longer issue paper to them. As long as these people suffer a few setbacks, they will no longer go to the public toilet to get paper, and this behavior will end.

Scan the QR code to follow the official account to pick up paper. You can install a QR code scanner in every public toilet to get paper. Every time you follow an official account, you can get a pack of paper. This can not only help pedestrians save money, but also make it easier for them to use public toilets. This kind of machine can only update one official account every day, and everyone can only receive one pack of paper per day by scanning the QR code. Now most people have begun to use smartphones, and everyone can scan the QR code to follow. There is no need to worry about not being able to play with mobile phones. If they really can't ask passers-by to help them scan the code, they can also successfully receive a pack of paper, which is completely convenient for them.

Ask the sweeper aunt for it. Every public toilet has aunties and uncles who clean it. These people are basically there all day long. If a visitor does not bring paper, he or she can ask the cleaning staff to ask for it. They will give them paper of different lengths according to each person's needs, thus avoiding unnecessary waste.
