The Payment Card Industry Data Security Standards includes several requirements that you can look for when assessing card processing software. Although there are many steps for better security your business can take that aren't included in the PCI's list of security functions, it still represents an important key to reducing vulnerabilities, since the various qualities include both technical practices and ongoing policies for the best response. In addition to following the standard's required measure, there are also basic security habits to follow, such as employee education and PC security.

Whether you're familiar with the PCI DSS or need a reminder, you can read over their official list of 12 requirements here. Some of these are as follows:

  1. Access Management: Giving sensitive cardholder data to too many employees could fundamentally reduce security. A good POS system may help businesses manage different accounts and allow only authorized persons to handle important information.
  2. Consistent improvements: Both the information security policy your company uses and the anti-virus tools you use for systems need to be not just effective from the start but also updated regularly. Since threats change and could affect new areas of an organization, every business needs to address their capabilities to continually protect data on a developing basis.
  3. Encryption: Point-to-point protection will close some of the gaps in a processor and leave the merchant at less of a liability. In a 2012 FAQ on this process, the PCI clarified that this form of encryption has to include security at the point of interaction, as well as encryption and decryption devices, applications and all methodologies used.

With compliant credit card software, your business will  have the tools to start transactions on a good foot and set a strong example for later on.
