MIFARE Plus® S 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 non-security relevant applications on existing
CRYPTO1 infrastructure minimizes 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 for 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. In
example for systems with multiple service providers that are using the same wallet and
clearing service, the Transaction MAC feature proves to the clearing house 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, system can freely choose to communicate in the native and APDU mode.
