The processor initiates operations using the interface circuitry as part of a transaction. The operations include receiving a certificate from a merchant system, encrypting the certificate, and sending the encrypted certificate to the merchant system with an instruction to forward the encrypted certificate to an authorization system for the payment card. An encrypted response is received. The encrypted response originates from the authorization system and is forwarded to the payment card by the merchant system. The merchant system is unable to decrypt the encrypted certificate and the encrypted response. The payment card decrypts the encrypted response and determines whether authentication of the merchant system is successful according to the response."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure payment card","description":"A payment card includes interface circuitry and a processor coupled to the interface circuitry.
