Researchers use shopping cart to put mobile, NFC payment theft on wheels

Using a shopping cart turned into an antenna, security researchers captured sensitive data from contactless payment cards, and concluded the wireless theft gear could easily be concealed in a backpack. In a recently published paper called Eavesdropping near-field contactless payments: a quantitative analysis, the researchers assessed eavesdropping attacks on contactless payment transaction for ease and success rates. They specifically made their easily concealable antenna using low-cost electronics.
