HF RFID Standards and Tag Descriptions

ISO15693

The ISO/IEC 15693 standard was developed for "Contactless Vicinity Cards". Adopted in
1998, ISO15693 has significantly enabled global acceptance of 13.56MHz RFID
technology. Based on contributions by Texas Instruments and Philips, ISO/IEC 15693 is
largely a superset of the features and specifications of the Tag-it HF and I·Code1
products, respectively.
• ISO15693-1: Defines the physical characteristics of a credit card transponder.
• ISO15693-2:
Specifies the 13.56MHz air interface and modulation methods that
accommodate regulatory bodies worldwide.
• ISO15693-3:
Specifies the command protocol and anti-collision method for data
exchange between tags and readers.
The ISO15693 "standard" permits tags to be manufactured that support optional and
custom commands, and that have custom memory structures, sizes and architectures.
The SkyeRead family of RFID readers fully supports all four (4) IC manufacturers that
offer ISO/IEC 15693 compatible tags.
Tag-It HF-I ISO15693 (Texas Instruments)
The complete Tag-It HF-I specification can be found in the Texas Instruments publication
titled "Tag-It HF-I Transponder Inlays Reference Guide".
