I'm an engineer by formation, with experience in applied cryptography, in particular in Smart Card systems. My current professional activity is in payment of Smart City services (e.g. public transport) with contactless Smart Cards and mobile devices.
Feel free to edit my answers to fix obvious errors, or improve them on expression (I'm not a native English speaker).
