Abstract (en)

[origin: FR2864296A1] The process involves preventing variations of electrical energy resources (VCC, VDD) supplying electric power to a portable intelligent object, through a contact interface and/or a contactless interface. The variation provokes selection of the external power source. The object communicates with an electronic data transmission terminal through the contact and/or contactless interfaces. Independent claims are also included for the following: (A) a device for preventing power variations provided to an object (B) transmission terminals contacting with a portable intelligent object (C) a portable intelligent object implementing a process of preventing power variations.
