Technical specifications of Philips CPU cards
The high security of Philips CPU cards is the core advantage of MIFARE Plus. It uses the AES algorithm with a 128-bit key length for authentication and encryption. At the same time, Philips CPU cards also include a series of other security features in their architecture. For example, Philips CPU cards use both random card serial numbers (RIDs) and 7-byte globally unique serial numbers (UIDs), which can be used to protect user information and prevent decryption by others.

Features of Philips CPU cards:

The Philips M1 card is widely used worldwide and has become an implicit "standard" for contactless IC cards. In 2008, German Studies announced the decryption of M1 series cards. To address the security issues caused by traditional M1 card decryption and to consider compatibility with system upgrades, a new generation of contactless smart CPU cards has been launched. For access control and payment systems with high security requirements, Philips CPU cards undoubtedly represent a breakthrough in terms of security and performance. Philips CPU cards offer a higher level of security than traditional M1 and IC card series, and are compatible with the M1 series. Notably, Philips CPU cards are now compatible with the new NFC technology, a new standard for future mobile payments.
