PKD-Related Project Documentation

Automated Border Control (ABC) systems can significantly improve efficiency and security of border management processes when properly implemented. In order for such benefits to be realized, it is vital that electronic Machine Readable Travel Documents (eMRTDs) presented to ABC systems are fully validated and that the digital signature is properly verified. There is, as a result, an important link between deployment of ABC systems and participation in the ICAO PKD.

ICAO Annex 9 Recommended Practice 3.33.5 indicates that data from the PKD should be used to validate eMRTDs during their processing in ABC systems.

In order to allow State authorities, airport authorities and other interested parties to undertake a cost-benefit analysis for the deployment of ABCs in their facilities, ICAO has developed a Cost-Benefit Analysis Tool for ABC systems. Further information on this tool is available here.
