After upgrading the system infrastructure, service operators can easily switch Mifare Plus-powered cards in the field to a higher security level without the need to revoke or re-issue the cards.

NXP Semiconductors has released Mifare Plus, a contactless smart card IC for the cost-sensitive automated fare collection (AFC) and access control markets.

Mifare Plus features multiple levels of security, including advanced encryption standard (AES) encryption and an easy migration path from existing Mifare Classic implementations.

"For both transport operators and passengers, Mifare Plus offers unprecedented levels of security, privacy, compatibility and performance for entry-level smart cards and is suitable for ticketing systems", said Henri Ardevol, General Manager, Automatic Fare Collection, NXP Semiconductors.

"The IC has been designed from the ground up to address the security and privacy needs of the 21st century and thus complements our current Mifare portfolio".

"With Mifare Plus, consumers can rest assured that their individual information cannot be tracked by others".

"For system integrators, Mifare Plus offers outstanding flexibility, supporting multiple levels of security for an easy upgrade path from existing Mifare Classic installations".

The backwards compatibility of Mifare Plus allows for a seamless introduction of cards in existing Mifare Classic implementations.

After upgrading the system infrastructure, service operators can easily switch Mifare Plus-powered cards in the field to a higher security level without the need to revoke or re-issue the cards.

Mifare Plus is the only smart card IC of its class to offer strong AES encryption for authentication, integrity and confidentiality, based on a 128bit key length.

Mifare Plus chips comprise a number of additional security features which, when used optimally in the infrastructure, provide for a system that prevents individuals from being identified and tracked by others.

These features are enabled through the support of secure random identifiers (RIDs) next to 7byte identifiers (UIDs).
