I’m not sure if you are already familiar with PCI DSS or Payment Card Industry Data Security Standard. If not, let me define it for you, It is a kind of a universal standard for security established by the PCI Security Standards Council. This  standard needs to be followed by any organization that uses, processes or sends information pertaining to the credit cards issued by companies like American Express, MasterCard,  and Visa.

Merchants become visa PCI compliant to comply with standards which does not actually guarantee or equal security. To date, a lot of merchants still get hacked because their credit card information could be hacked within their environment. However, there are already new solutions for this problem, one of those I know is the BrainTree’s.
