About 13.56Mhz NFC Card

The 13.56Mhz NFC Card is the core part of the NFC smart card. The manufacturing process of smart cards mainly includes in-card integrated circuit design, software design, making circuits on monocrystalline silicon wafers, testing and writing information in E2PROM, grinding wafers, micro-modules, card manufacturing, card initialization, processing and distribution. . More than half of them are related to chip manufacturing.

The E-Ticket NFC Card is a semiconductor silicon wafer made by an advanced microfabrication method. Silicon wafers contain large scale integrated circuits.

NFC smart card chip is a passive NFC chip, does not require a battery, u data transfer speed is fast, 106kbit / s, u data can be kept for 10 years, rewritable times 100,000 times, u each device has a unique 4 bytes Serial number, u need to pass the triple authentication (ISO/IEC DIS9798-2) (Mutual three pass authentication), data stream encryption of uRF channel, protection against eavesdropping attacks, two independent keys in each zone (per application) Support multi-application with key Hierarchy, u provide transport key protects access to EEPROM on chip delivery when submitting to users, double-density for each zone The key supports the hierarchical key system and can implement the application requirements of the multi-wallet function.
