The Belling BL75R06SM manual describes the 8 KB EEPROM contactless encrypted storage card, its features, interface, security and memory operations.
The BL75R06SM is a contactless encrypted storage card chip that integrates an RF communication interface, a security control unit and an 8 KB EEPROM. It is intended for use in ID cards, e‑wallets, automatic fare collection and public‑transport ticketing systems and complies with the ISO/IEC 14443 Type A standard.
The document details the chip’s memory architecture (16 sectors, 4 blocks per sector, 16 bytes per block), the command set for reading, writing, incrementing, decrementing, restoring and transferring data, and the three‑stage mutual authentication mechanism that secures all data transfers. This manual is written in Chinese.
