We have explored the cyber attack on the Target Point of Sale (POS) systems that resulted in 40 million customers having their credit card information stolen. There have been some changes in the way we use a credit card in stores now -- using the chip reader instead of the swipe reader.

Answer the following questions on the discussion board:

• Does the chip reader make the transaction safer?
• What can companies do to prevent a cyber attack like what Target experienced?
• What can consumers do to protect themselves at the point of sale?
