Machine-to-machine (M2M) is the communication between machines that aims to structure processes faster, more efficiently and more securely, and open up new business segments.
The key technology in this respect is wireless communication, that enables universal data transmission, remote control, remote diagnostics and remote maintenance for individual modules or entire systems worldwide.
Put simply, data can be shared automatically using a sensor, for instance, which is mounted on a machine; this sensor records information on the device status or the environmental conditions. A SIM card is used to transfer the information to a central control center where an application provides information and enables activities to be initiated.
Of course, in M2M applications there is a key role for security, ensuring that data is sent safely to and from the devices and the central system. M2M and IoT applications can only produce long-lasting success if there is a suitable security strategy.
