Magnetic stripes is defenseless

Robert Siciliano, CEO of IDTheftSecurity.com and a security consultant: "Electronic funds transfers at the point of sale [EFTPOS] skimming is a relatively new scam that has become more prevalent over the past few years. POS machines are particularly vulnerable because the magnetic-stripe technology, which has been around for 40 years, is essentially defenseless against modern fraud techniques," http://alturl.com/x4tx7

I cannot understand why merchants are still having magnet tripe readers in POS terminals in their stores. Of course they will be focus for fraud when it now is the weakest animal i the pack because of the enforcement of PCI DSS i the back-end systems.
