First I share one story heard from my friend. He was working for UBS at the moment where the employee needs to insert a security card into the laptop in order to login to the computer. But unfortunately the card reader was put just under the CD drive. And there are two slots: one for CD drive and the other for the card reader. Frequently employees insert the card into the slot where usually a CD should be inserted and the employee has no choice but to call the IT help desk. Luckily we don't have CD drive any more in many laptops.
