I strongly disagree with your idea, in my opinion entering a chip in the body can disrupt the health of the body. you should look for ideas about better technology.
Yes, you're right. sooner or later putting a chip in the body will harm to our health. I don't this we should allow it in the future. There are millions way to pay in the future but not micro chip.
Technology evolves from time to time and so what if in future they can implant chips without any health concerns? I don't in any way think that those suggesting this and trying to implement it did not factor in health related problems and so we shouldn't be conclusive.
