Stars attach great importance to the protection of privacy. When they go out, they often wear sunglasses masks and long trench coats to prevent others from taking pictures. The privacy of stars must include all aspects, and even the receipt of consumption is an important part of privacy. Therefore, stars often throw away all receipts, because receipts will expose a person's privacy and even involve security issues. Even ordinary people will tear up the consumption receipt in time, because it may contain some financial information, and even ordinary people are reluctant to expose their consumption privacy because it involves security issues.

1. A star's consumption receipt can reveal the privacy of some stars and be taken away by fans. For crazy fans, every move of a star can touch their hearts. If a paparazzi finds a star's consumption receipt, and then vigorously hypes it, saying how much the star ate at a meal, who the star invited to dinner, how many rooms the star opened, how many clothes the star bought, and how much the star spent on others, these contents can be found out in minutes, so the star will not keep it for himself unless it is deliberately hyped.

2. Now there are sometimes QR codes on the receipts. For example, the train ticket has its own information on it, so the consumption receipt should be torn up in time, otherwise it will expose some financial links. Some people have a high level of IT, but they don't use the right way. When they see loopholes in some places, they will think about drilling them. In case such people invade some paid software, there may be economic losses.

In fact, there are many people who pay by mobile phone now, and it is risky to keep many paid receipts, so whether you are a star or not, you should beware of losing them. It is very important for people to get rid of small tickets in time. Now, even ordinary people should protect their privacy, because we live in the Internet age.
