What is Mifare UID?
Mifare Card Serial Number is the unique identifier defined in ISO 14443-3A. There are 3 types of UID defined in the standard – single (4 bytes), double (7 bytes) and triple (10 bytes). Only in first versions of the Mifare card, the UID was 4 bytes but now have migrated to 7 bytes.
What is the difference between Mifare and DESFire?
MIFARE DESFire chips contain a full microprocessor, and with much more robust security features compared to MIFARE Classic. These cards contain an on-chip backup management system and mutual three pass authentication, the EV1 smart card can hold up to 28 different applications and 32 files per application.
How do DESFire cards work?
MIFARE is a contactless card technology that was introduced in 1994. All MIFARE cards comply with the ISO14443A industry-standard requirement and, like other contactless cards, use an internal antenna and chip that reacts once a card is within the magnetic field of a reader.
What does Mifare stand for?
MIkron FARE Collection System
MIFARE (derived from the term MIkron FARE Collection System) is NXP’s well-known brand of passive RFID chip used in RFID cards and tags with a typical read/write distance of 10 cm (4 inches).
Are Mifare cards secure?
In its highest security level SL3, using 128-bit AES encryption, MIFARE Plus is secured from attacks.
What is the difference between proximity card and MIFARE card?
MIFARE cards have three main differences from a standard proximity card: The frequency of a MIFARE card is 13.56 Mhz. A MIFARE card has memory for storing values (typically up to 1 kilobyte of data). A proximity card does not have the capacity to store values.
Where is Mifare used?
MIFARE Classic family They are ASIC-based and have limited computational power. Due to their reliability and low cost, those cards are widely used for electronic wallets, access control, corporate ID cards, transportation or stadium ticketing.
