What is PCI Compliance?
The Payment Card Industry Data Security Standard (PCI DSS) is a set of requirements intended to ensure that all companies that process, store, or transmit credit card information maintain a secure environment by adhering to PCI Compliance Standards.
Being PCI Compliant means that your systems are secure, and your customers can trust you with their sensitive payment card information.
For more information about PCI compliance, see 
Official PCI Security Standards Council Site.
How do I become PCI Compliant?
You must work with your payment processor to help ensure that your business is PCI compliant. Your business must comply with your merchant processor’s PCI requirements.
If you need any assistance completing or submitting related forms or questionnaires for PCI compliance, please reach out to your merchant processor. After all requirements have been completed and your business has passed all assessments, your business is fully validated as PCI compliant.
Note: depending on your processor, a PCI fee may be billed depending on the structure of your merchant account and non-compliant businesses may incur penalties and run the risk of data breaches. For more information about PCI fees, see Merchant processing fees.
