Secure payment acceptance explained for business owners.
Chip cards, security validation, tokenization, and encryption all play a role in safer acceptance. CMS explains the practical pieces in plain language, then keeps next steps on CMS pages — including the Security & PCI hub for annual validation.
Open Security & PCI →Practical building blocks
You do not need to become a security engineer. These are the concepts that most often show up when merchants ask how to take cards more safely.
Chip cards (EMV)
Chip-enabled acceptance helps authenticate in-person transactions and supports modern liability and security practices at the counter.
Security validation
Merchants remain responsible for applicable card-data security validation. CMS explains requirements without burying you in acronyms.
Tokenization
Tokenization can reduce exposure by replacing sensitive card data with a token in supported payment workflows such as card-on-file.
Point-to-point encryption
Validated encryption can reduce payment-data exposure and may help reduce security scope when properly implemented with your enrolled setup.
