New technologies have always been important in ICAR forums for members to understand and discuss. In this conference electronic identification and measurement, DNA recording, and internet services were debated, with an exchange of experiences by the delegates. Finally, new strategies for potential new services for the ICAR member organisations were discussed. One such proposal was for an international benchmarking service for measuring and comparing the activities of ICAR organizations."
