Abstract
The dual frequency RF identification device comprises an HF antenna for receiving an HF electromagnetic field, an HF interface, an UHF antenna for receiving an UHF electromagnetic field, an UHF interface, non-volatile memory means formed by a first non-volatile memory and a second non-volatile memory. The first non-volatile memory can be in an active state without the second non-volatile memory being powered and consumes substantially more power than this second non-volatile memory. The first non-volatile memory comprises all data needed for a device configuration allowing this device to carry out at least a communication mode of an UHF protocol, this communication mode having access to the first non-volatile memory but not to the second non-volatile memory. The first non-volatile memory further comprises all attributes needed for a configuration of this communication mode.
