Implementation Best Practices

• Use ECC for new deployments to reduce key sizes and improve performance.
• Implement GlobalPlatform Secure Channel for OTA and personalization security.
• Design for minimal attack surface: limit exposed APDUs and enforce strict input validation.
• Maintain separation of payment and third-party applets via firewalls and secure channels.
• Keep cryptographic libraries up to date and follow payment scheme mandates.

• EMV payment cards implement Application Identifiers (AIDs), Data Authentication (SDA/DDA/CCA/eDDA), cryptograms (ARQC/TC/ARPC), and cardholder/issuer data (EMV static data, PAN, expiry, discretionary data). Cryptographic operations rely on issuer keys and secure key management (HSMs, SKIs, key injection).
• Proper EMV implementations require adherence to EMVCo specifications (Contact, Contactless, Level 2 kernels, Security Evaluation Process, Certificate Issuance) and type approval testing. EMVCo maintains and updates these documents; access to many technical documents requires membership or login.
