Questions tagged [iso-15693]

ISO/IEC 15693 is a series of ISO standards for vicinity coupling RFID systems.

ISO/IEC 15693 is a series of ISO standards for vicinity coupling RFID systems. These standards define the interaction between vicinity cards/tags and reader devices.

Vicinity coupling systems operate in the 13.56 MHz frequency band. Compared to proximity coupling systems and NFC (which also operate on 13.56 MHz), vicinity coupling systems offer larger read distances (typically 1--1.5 meters).

Eventhough this standard is not directly part of , as of today, many devices support (parts of) the ISO/IEC 15693 standard.
