ISO standards

The ISO organization devotes itself to definition and promotion of worldwide-recognized

standards in the contactless area. 3 standards for objects operating in the 13.56 MHz

frequency range have already been approved (ISO SC17 on identification cards and related

devices):

●

ISO10536 identification cards and contactless integrated circuits cards:

–

Close-coupling cards (reading range below 2 cm).

●

ISO 14443 identification cards and contactless integrated circuits cards:

–

Proximity cards (reading range up to 20 cm).

●

ISO 15693 identification cards and contactless integrated circuits cards:

–

Vicinity cards (reading range up to 1 m).

This standard is part of the future SC31/ISO18000 standard, currently under

discussion.

ISO standards are recognized worldwide and guarantee the full interoperability of

transponders and readers from different suppliers.

ISO compatibility for ST devices

ST contactless memories are ISO-compatible:

●

ISO 14443 type B for short-range devices

●

ISO 15693 or ISO18000-3 Mode 1 for long-range devices.

This application note refers to ST ISO 14443B short range RFID.
