The extreme proliferation of POS systems in today's retail marketplace may make them an established feature of the sales landscape, but this familiarity also leaves them more at risk to the malicious whims of hackers.  It's up to businesses to ensure that they utilize the most secure credit card payment software and prevent identity thieves from taking advantage of their infrastructure. 

A recent article by Engineering and Technology magazine detailed the particular means by which criminals are able to compromise such setups and listed notable past examples of such cases. According to a recent global report mentioned in the article, the retail sector accounted for 45 percent of data breaches investigated by a certain security firm. Between 2008 and 2011, a group of Romanian hackers were supposedly able to extract $3 million from the sandwich chain Subway, though all were later apprehended.  

There are a variety of ways those with diabolical purposes can target shops and small companies. One method that has proven especially damaging to the industry is the use of duplicated bank cards to obtain payment information. Some criminals are even able to create cloned cards through a swipe terminal, as happened with more than 60 Barnes and Noble locations last year.

McAfee's director of security Dave Marcus warned that this method is very attractive to identity thieves and most likely to remain the trend for the foreseeable future. "Instead of coming in with guns and robbing the till, criminals can target businesses, root them from across the planet, and steal digitally," Marcus told E & T. 

The best credit card POS software will come with protections that allow for barriers against abuse. Companies of all sizes are advised to consider the security features of their systems carefully in order to prevent fraud from affecting them.
