DESCRIPTION:*Abstract:*\nWe present a quantitative assessment in terms of 
 frame error rates for the\nsuccess of an eavesdropping attack on a contact
 less transaction using easily\nconcealable antennas and low cost electroni
 cs. An inductive loop\, similar\nin size to those found in mobile devices 
 equipped with NFC capabilities\,\nwas used to emulate an ISO 14443 transmi
 ssion.  For eavesdropping we used an\nidentical loop antenna as well as a 
 modified shopping trolley.  Synchronisation\nand frame recovery were imple
 mented in software. As a principal result of\nour experiments we present t
 he FER achieved over a range of eavesdropping\ndistances\, up to 1m\, at d
 ifferent magnetic field strengths within the range\nspecified by the ISO 1
 4443 standard.\n\n*Bio:*\nThomas is a PhD candidate at the University of S
 urrey\, looking into the\nsecurity and privacy of near field contactless p
 ayments. He is currently\ninvestigating how a combination of remote interr
 ogation and eavesdropping\ncould be used to extract information from conta
 ctless devices that could\npotentially cause financial or anonymity loss f
 or the victim. Following his\nmilitary service\, he studied for a BEng in 
 electrical engineering from the\nUniversity of Sheffield and an MSc in com
 munications and signal processing\nfrom the University of Bristol.
