Patent ID: 7741956

Claim:
A method of reading information from different types of tags in an RFID system using an RFID reader, comprising: radiating, from an antenna of a transmitter of said RFID reader, a propagating radio frequency (RF) signal to a first tag of a first type and to a second tag of a second type, said first and second tags of said first and second types configured to employ respective first and second encoding schemes for generating first and second encoded RF signals; receiving, by said RFID reader, the first and second encoded RF signals propagated from said first and second tags of said first and second types, said first and second encoded RF signals containing information associated with the first tag and information associated with the second tag; demodulating the first and second encoded radio RF signals to generate demodulated first and second demodulated signals; and decoding the demodulated first and second demodulated signals to extract said information associated with the first tag and said information associated with the second tag.
