Abstract: Autonomous system for the remote management of pay-for-use devices, such as printers, fax machines, scanners, servers and routers, among others, constituted by electronic devices (1), of reduced size, connected to each of the remote units (4) to be managed, capable of reading the meter value, processing and storing the information and sending it, through one or several existing communications networks (2), to a collection centre (3). Specifically, said device (1) has an interface for connection to the ETHERNET network for sending and receiving electronic mail via Internet, or for configuring the device itself through a server accessing its web page, and a GSM modem for sending the information by means of calls or short messages via radio. Also, the Flash EEPROM and dynamic RAM allow the software required by the system and the data storage respectively to be run.
