Convergent Software Develops Industry's First RFID Encoded Data Diagnostic Tool |
|
|
[02/07/08]
The diagnostic tool addresses one of the challenges of RFID technology. This is to ensure that data is properly encoded on the tag in a compliant manner with an application standard. Its major feature is that it identifies potential encoding errors in the following features:
Data validation to be compliant with the application standard
Data compaction
Encoding of data formats and object identifiers
Syntax to be compliant with the ISO/IEC 15962 encoding rules
Whether a sub-optimum compaction scheme has been used
The software produces HTML reports showing the results of encoding and decoding. The error reports from the diagnostic tool provide an electronic record of the errors found so that these reports can be exchanged between the airport and airline implementing the RFID data capture application and the organisation responsible for creating the error.
The diagnostic tool has been designed to improve the robustness of RFID technology by addressing a neglected part of applications - the encoding of data. It provides another tool to improve the robustness of RFID technology in open systems applications, where an organisation reading the content of the RFID tag has to rely on accurate encoding of data sourced by a different organisation.
About ISO/IEC 15962
ISO/IEC 15962 provides a set of data encoding rules for RFID tags. These rules have been designed to support the encoding of data from different application domains, so that legacy data used in bar code can easily be applied to RFID, and new types of data can be applied to RFID tags. The ISO/IEC 15962 encoding rules are independent of both the application data and the particular RFID tag architecture. This means that various types of application can be supported. Besides the IATA application, the encoding rules have so far been adopted in the library community and in the automotive industry. The different types of tag architecture are supported through a mechanism called a Tag Driver, which understands the formatting rules of different types of tag. This enables the encoded byte stream to be organised correctly, even to the extent of selectively locking some of the data.
ISO/IEC 15962 (and its companion standard ISO/IEC 15961, dealing with application commands), were first published in October 2004. Both the standards are currently being revised by ISO to support new encoding techniques and tag architectures that have been developed since the first publication.
