New passport, same fears
Economist.com | Border controls
One approach is to imprison the chip in a Faraday cage. This is a contraption for blocking radio waves which is named after one of the 19th-century pioneers of electrical technology. It consists of a box made of closely spaced metal bars. In practice, an aluminium sheath would be woven into the cover of the passport. This would stop energy from the reader reaching the chip while the passport is closed.
