Opinions are sharply divided over weather the governments' decision of introducing the idea of microchip implants to people would be wise or not. From my point of view, such a scheme could be either useful or hazardous for the people.
Ideally, the world would be a better place if we all had an implanted chip ID. This would be the perfect solution so that people never have to worry about losing their ID card or stop and check that they have it in their purse or wallet. Unfortunately, the world is an imperfect place with bad people living in it and the introduction of a microchip implanted on everybody would be detrimental whatsoever. That is because the chip has no power source but it contains digital data which can be accessed when the chip is in close proximity to a scanner. In addition, it would not be difficult for criminals to use concealed scanners on a crowded subway train, for instance, to retrieve information on people's chips. Consequently, it would be quite straightforward for them to write their own chip and begin pretending to be you which could possibly result in a disastrous confusion.
Moreover, these ID card substitutes might seam like a good idea in the present, but the future is unknown. In particular, even though we live in a democratic government now, there is no guarantee that it will last forever. If democracy gives way to dictatorship, the dictator will be delighted that everyone has a chip and all the details are kept on a central computer allowing him/her to manipulate everyone.Furthermore, from an ethical standpoint, monitoring people with RFIDs means treating people as livestock or industrial goods, thereby breaching the right to dignity and privacy they have as human beings. Last but not least, as far as the society is concerned, it would be vulnerable to a great extent. Meaning that, right after the chip implant idea is suggested to the people they are going to be divided into two groups, the supporters and the opponents of the scheme. Ultimately, not only will there be a conflict between them but it will also lead to a disturbance of the societal balance.
In a nutshell, as I see it, there could be plenty of argumentations regarding the effectiveness of microchip implants in every societyb at the end of the day the drawbacks are always going to outweigh the benefits.
