Eat me, drink me

Millions of people have reading difficulties or poor eyesight, so they can’t
read medicine labels properly and risk taking the wrong drug. To overcome this
problem, En-Vision America of Normal, Illinois, has created talking medicine
bottles. The company has developed a printer which embeds a microchip in the
label as it is printed. The patient later points a hand-held voice synthesiser
at the label, which uses a beam of radio waves to scan the microchip and read
its message out loud.
