Near Field Communication (NFC) is a wireless communication technology for convenient and secure data exchange over a short distance. Use cases can be found in a wide range of different applications like access control, payment, public transport, fare collection, data sharing, smart poster and many more. Due to the different requirements, standards and implementations of the contactless interface, interoperability can not be guaranteed.
To test interoperability in the field of secure payment the device under test performs several payment transaction at different positions for many different payment terminals. If a transaction error occurs the communication between the two NFC devices needs to be further analyzed. Besides the communication relevant parameters the protocol layer needs to be analyzed. In this thesis, you will work with the communication protocols of secure payment applications using NFC technology. Two steps are necessary to analyze the protocol between two NFC-enabled devices. First, the generated electromagnetic field should be captured with a sniffer coil and preprocessed. Second, the signal should be analyzed using the ISO 14443 standard. .
