(ETH)- This question seems to keep coming up year after year as some see microchips implanted in humans as the wave of the future. Others see an uncertain path with questions about privacy and ethics. Microchipping has gained some popularity in Sweden which already has a robust digital society.

A few companies in the U.S. have also tried it with their workers on a voluntary basis. “One of the biggest concerns is the unintended consequences of the ability to track where bodies are in the most fundamental sense,” warns Associate Professor Michael Zimmer, PhD with the Dept. of Computer Science at Marquette University. He has researched privacy issues and ethics related to technology.

They could also be used to hold medical information and could be very helpful in emergencies. READ MORE
