How to treat hotel sheets with chips?

I think it's a good idea to insert a chip into hotel sheets, and then guests can know how many times the sheets have been washed and whether they have been washed, but it's very difficult to implement. How to ensure that this data will not be tampered with and how to realize this idea at a reasonable cost, I think there are still many technical requirements.

There are too many Internet startups now, and the most important thing for Internet startups is creativity and practicality. Creative things may attract many people at first, but if they are useless, their popularity will decrease. Just like enjoying an umbrella some time ago. If it rains, everyone will take a taxi back, and girls will take umbrellas. This is very unrealistic and has not been implemented.

* * * The idea of enjoying cycling was good, but it later became a big capital game. Many small businesses have been dragged down, and they have to pay a deposit at the beginning, so they all come out to share a piece of the action. But later, it was all about price war and bicycle delivery rate. That's throwing money at you. There is no other way but to rely on big capital. Finally there are two left, one is Bazaro, the other is Xiaohong and Xiaolan. It's also hard.

So I really don't know if this idea will succeed. I think the key point is the credibility of this information. How can we believe that the data you gave is true? You can set an immutable thing for the chip, which will be sensed as soon as it enters the washing machine. I think it's possible. Moreover, whether this chip will reveal the privacy of others, and how to make others trust the company that put the chip in it is also very important, so I think this project needs to be well planned.
