MIFARE Plus EV1 2K Card. Migrate Classic contactless smart card systems to the next security level with the next evolution of the proven MIFARE Plus product family. MIFARE Plus EV1 brings benchmark security and additional features to mainstream contactless smart card applications. It is the only mainstream IC compatible with MIFARE^® Classic^® EV1 1K (MF1S50yyX/V1), MIFARE Classic EV1 4K (MF1S70yyX/V1), and the MIFARE Plus EV0 product family (MF1PLUSx0y1 and MF1SPLUSx0y1) which offers a seamless upgrade path for existing infrastructure and services. MIFARE Plus EV1 enables system operators to selectively upgrade security-relevant applications. The ability to operate nonsecurity relevant applications on existing CRYPTO1 infrastructure minimizes the total cost of ownership (TCO) for the whole infrastructure eco-system. After switching to Security Level 3, MIFARE Plus EV1 uses Advanced Encryption Standard (AES) based on open global standards for cryptographic methods for authentication, data integrity protection, and data encryption. Variants with EEPROM sizes up to 4K cater to the growing number of contactless applications and thus growing memory needs. This support empowers system operators to add future applications as needed while relying on an established product standard. The use of the MIFARE Application Directory (MAD) simplifies the future on-boarding of new applications on a MIFARE Plus EV1. AES for data encryption and integrity protection is also used for the secure end-to-end channel communication capabilities of MIFARE Plus EV1. This new evolution allows system operators to remotely manage card content over-the-air, even for Crypto1 operated applications. Additional applications and services can thus be created remotely after card issuance in a secure way, further enhancing TCO. The Transaction MAC feature securely verifies the authenticity of a transaction. An example for systems with multiple service providers that are using the same wallet and clearing service, the Transaction MAC feature proves to the clearinghouse that transactions between service providers and customers are genuine. It can also be used to verify transactions in numerous offline scenarios or where real-time online authentication capabilities are not feasible for system operators. For easy integration with mobile devices and other convergence media, MIFARE Plus EV1 also supports communication via ISO/IEC 7816-4 APDUs. To increase flexibility, the system can freely choose to communicate in the native and APDU mode.
