Transponder classes and generations

The transponder classes are distinguished by the different communication protocols used
between the reader and transponder. Transponder classes are mostly mutually incompatible.
The following transponder classes are supported by the RF 600 system:
● ISO 18000-6B with full ISO profile (RF660R, RF610M)
● EPC Global Class 1, Gen 1 with full EPC Global Profile (RF660R, RF610M)
● EPC Global Class 1 Gen 2 with full EPC Global Profile (ISO 18000-6C)
Support for protocol types using the RF600
Specification of the transponders/tags in accordance with ISO 18000-6 refers to
implementation of the air-interface protocols.
There are three variants:
● ISO 18000-6A: Not supported
● ISO 18000-6B: Supported by RF660R
● ISO 18000-6C: Supported by RF660R, RF620R, RF630R
