What you can do to
protect yourself
as a merchant

Payment card security is a responsibility in which you must share. Mastercard® has laid the foundation for a successful security platform and provides tools that empower retailers to make a difference.

Businesses accepting Mastercard cards must comply with basic security practices. Mastercard cardholders expect their transactions to be processed securely. And your acquirer should monitor your transactions to ensure that you fulfil your obligations. To help protect your business and your customers, Mastercard highly recommends that you take the precautions established by the payment card industry to secure personal account and transaction data.

Retailers must do their part to protect their business and their customers.
