8.5 Data integrity

Following mechanisms are implemented in the contactless communication link between

interrogator and label to ensure very reliable data transmission:

• 16-bit CRC per block

• Bit count checking

• Bit coding to distinguish between “1”, “0” and no information

• Channel monitoring (protocol sequence and bit stream analysis)

8.6 RF interface

The definition of the RF interface is according to the standard ISO/IEC 15693-2 and

ISO/IEC

15693-3.
