Convergent Software works closely with RFID-related standards and develops data encoding and privacy compliance software to support and encourage the correct use of RFID.

RFID in Libraries

- Tag Simulator.

ISO 28560-2 has been designed to extend the functions of using RFID in libraries. It allows a lot of flexibility to cope with different scenarios. For example:

  • Initial procurement of books
  • Individual loan
  • Inter-library loans
  • Sets of items
The flexibility of this standard, both in terms of being able to select which data elements to encode and the sequence in which they are encoded, allows libraries to extend the functions of using RFID.

The Problem

How to decide what to encode?

Whilst the flexibility of ISO 28560-2 is one of its greatest strengths, it also creates a problem for libraries. How do you decide what to encode and in what sequence? How do you decide which data elements to lock? While national data profiles can be helpful with the selection process, they really only advise on up-grading some optional data elements to being required and on not using others. These data models are generally silent on the sequence of encoding – a feature which can impact on reading efficiency.

Libraries have to make their own decisions about:

  • the data elements required to support potential library functions
  • the sequence in which data elements are encoded, taking account of a configuration of data to suit different operational functions
  • the implications of locking data elements

The Solution

Convergent Software's Tag Simulator helps you get the best for you RFID system by allowing you to determine the best set of data to encode on your RFID tags to best meet your requirements.

The Tag Simulator allows you to trial different configurations of data elements (including deciding which you want to lock) and simulating the encoding process. You can trial as many different configurations as you like to match all of your RFID scenarios. You can even save your configurations for later use. The process of modelling different encoding configurations can also help in deciding what type of tag stock you need in your solution because the Tag Simulator lets you know how many blocks of data will be required to encode your data. This information can then be used in your RFID tag buying decisions.

The Tag Simulator produces a report on the encoding. This can be saved in PDF format and can then be sent to your (prospective) RFID system supplier.

The Tag Simulator empowers library management before any investment in RFID tags or hardware.

The Tag Simulator also validates all of your input data against the rules of ISO 28560-2. This can identify issues very early in your RFID adoption/conversion process and save you from a lot of problems downstream. The software also assists with the entry of more complex data elements (e.g. Set Information) so you don't need a detailed understanding of how these work in ISO 28560-2.

When you purchase the Tag Simulator, you will also gain access to a document describing all of the ISO 28560-2 data elements, with our guidance on how best to use them.


To maximise the ROI of RFID in your library you need to take control of what you are encoding on your tags, before you are tied into an inflexible system from your RFID vendor.

The Tag Simulator can be a powerful tool in aiding your discussions with (prospective) RFID system vendors. You can use it to gain a clear understanding of how the flexibility of ISO 28560-2 can be best put to use to maximise your return on investment. Your RFID system will be expensive. They always are. Why settle for less than the best fit for your requirements? For a very small investment, you can use the Tag Simulator to find that best fit and communicate that information to your chosen RFID vendor or even include your specific requirements in your invitation to tender.


The Tag Simulator cost only £250 for an outright, single-user licence.
