Abstract: The invention concerns methods, systems and devices for transferring, by electromagnetic linkage, data between universal readers and badges with different communication protocols. The universal reader searches for the nomadic objects by emitting a scanning signal of modulation modes. Each nomadic object, receiving the scanning signal, produces an echo signal, according to its own particular protocol. The universal reader analyzes each echo signal and deduces therefrom the specific protocol applied by the nomadic object. The universal reader inserts in universal reader inserts in conformity with the specific protocol, the messages to be transmitted in the reader frames interpretable by the nomadic object.
