Abstract: The invention relates to a method of controlling a device able to function in a mode with code verification or in a mode without code verification to effect a transaction, the method including a step of authenticating the device, an optional step of verifying a code, and a stage of continuing the transaction, wherein the method further includes a first verification step of verifying whether the device is functioning in the mode without code verification; and if so, the stage of continuing the transaction includes a step of making the transaction secure including determining a history of preceding transactions of the device in the mode without code verification, processing the transaction securely as a function at least of the history, and updating the history. The invention relates to a device able to function in accordance with such a control method.

Abstract: An electronic device, such as a mini card, has an inlay substrate for the electronic device. The inlay includes a substrate layer, a communication interface having a first metallization supported by the substrate layer, a hole or a hole location area, for attachment to an external device, and a second metallization surrounding at least partially the hole or its location area. The second metallization strengthens the card at the hole area. The method includes realizing the first and second metallizations on the same machine and/or at the same time.
