Abstract
A piece of electronic equipment including a first subsystem such as a touch-sensitive tablet and a second subsystem such as a payment terminal. The first sub-system embeds a first operating system for managing the power consumption of the first subsystem. The second subsystem embeds a specific and secure operating system capable of executing payment transactions. Since the two subsystems execute two different operating systems, an operating state of one of the subsystems may not allow the required service to be implemented if this requires the use of resources implemented by both of the two subsystems. Thus the first and second subsystems exchange data relating to their respective operating state and, where appropriate, change their current operating state as a function of the data relating to an operating state of the other subsystem thus exchanged.
