Appendix B  
HF RFID Standards and Tag Descriptions 

 

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.

publication titled “Tag-It HF-I Transponder Inlays Reference Guide”.

The user can permanently lock any 
block.  
 
Once a block is locked, it can not 
be unlocked. 

 
A 64-bit ID (factory programmed) uniquely identifies each Tag-It HF-I chip.
