Abstract: For carrying out more energy to passive tag, a modified-Manchester coding is presented for RFID system in this paper. The basic idea of this coding is to provide more high level duration within a symbol cycle. The merits of being easy to synchronize and extract timing clock is still kept down. The cost of carrying more energy is that the frequency spectrum is widened.

Key words: RFID, coding, energy
