What Is Mifare S70-4K?
The Mifare S70-4K is a high-frequency RFID smart card that operates at 13.56 MHz and complies with the ISO/IEC 14443 Type A standard. Unlike its predecessor, the S50-1K, which offers 1KB of memory, the Mifare S70-4K boasts an expanded 4KB EEPROM storage, divided into 40 secure sectors. Each sector can be independently secured using unique keys, making the card highly customizable and secure.
