Category descriptions

Description of a category to which RFID standards can be assigned. Usually related to their field of application.

Data standards

The data standards address the way data is held in business applications. As such, they are associated with the data dictionaries developed by user organisations for encoding in various AIDC data carriers. In some cases, the legacy requirements of encoding in bar code need to be taken into account with encoding in RFID; in other cases, slightly new approaches can be adopted.

Data encoding and protocol standards (often called middleware)

The data encoding and protocol standards address the various types of communication between the RFID interrogator and the application, with the exception of not dealing with the device interface an

Device interface standards

The device interface standards and the data application interface protocol standard (see 7.8) are closely related.

Conformance and performance standards

There are two primary types of standard within this category:

Health and Safety regulations

There are two primary Health and Safety aspects associated with the use of RFID:

Frequency regulations

The frequency regulations govern specific aspects of radio spectrum and permitted power for an RFID system or other radio communication system. Therefore, radio regulations – as they are commonly called – have a direct and indirect impact on the use of RFID technology.

Data protection and privacy regulations

There is significant confusion among the general public – and even legislators – about data held on an RFID tag and the ability to track individual people using the air interface protocol.

RFID Air interface standards

The air interface standard primarily affects the components of the RFID system: the interrogator and the tag by defining rules for communication between the two devices. In particular, an air interface standard specifies:

Sensor standards

Often the term "sensor" is used in an imprecise and ambiguous manner. At one extreme this term includes RFID tags that only encode data; another accepts sensors correctly as being within the class of transducers and actuators but ignores significant differences in the means of communication from the sensor to the application and the topology of a sensor network.
