Migrate contactless systems to the next security level using NXP’s MIFARE Plus ICs. It offers the benefit of a seamless upgrade of existing MIFARE Classic® product-based installations and services with minimum effort. This results in the possibility to issue smart cards, being backward compatible with MIFARE Classic, into existing system environments before infrastructure security upgrades. After the security upgrade, the MIFARE Plus products use AES security for authentication, data integrity, and encryption that is based on open, global standards. The latest addition to the MIFARE Plus family is the MIFARE Plus EV1 contactless IC, offering an enhanced feature set on the highest security level.
