During years, many different researches and attacks against digital and physical payment methods have been discussed. New security techniques and methodologies such as tokenization process attempts to reduce or prevent fraudulent transactions.
The first time I’ve heard about RFID was at high school, back in 2002, when I was studying Electronics. Back in that time, this technology was like some sort of black magic to me. A few years later in 2011, our government in Argentina decided to implement a “new technology” called NFC, designed as the new and only way of payment for the use of public transport. So, I decided to understand it better, play with it, and try some hacks I heard from the cool people of the CCC.
