The machine's payment system supports Bluetooth Low Energy (BLE) and Near Field Communication (NFC) technologies, it enables a user to connect them to the machine as well as make payment using their smartphone.


“With a macro inspection of all the reversed sources I found huge portion of clean code — without obfuscation — that meant no great counter-measures adopted to protect user data and make the App secure at all,“ Pisani notes.

Prior to making the findings public, Pisani had informed the company about the flaws in their payment system.
