METHOD FOR SWAPPING BETWEEN TWO VERSIONS OF A SAME APPLICATION WITHIN AN INFORMATION PROCESSING DEVICE, AND SAID DEVICE

摘要

The invention pertains to the field of secured information processing devices, such as smart cards, and more particularly to the means for updating an application stored in a ROM (Read Only Memory) of such a device, and relates to an information processing device containing two versions of an application in the read-only memory thereof. The two versions have the same identifier. The device is provided with a means for controlling a swapping operation between said two versions so that the version of the application executed in response to a prompt of the application identifier can change.
