Abstract: The present invention relates to a method and a system for a universal application for transaction procedures with NFC technology. This application allows to realize an application distribution network for accessing services by means of mobile terminals provided with a proximity wireless communication technology or “proximity based communication protocol” (e.g. NFC, Bluetooth, RFID). The present invention envisages a “universal” mobile application, which is capable of modifying its function for each real application used, in terms of process and user interface (or “user experience”), e.g. menu layout, colors, logos, functionalities, commands.
