1. An RFD reader capable of:
- encoding information in terms of RFID symbols;
encoding the RFID symbols into successive waveform segments that individually correspond to the RFID symbols, the last one of the segments incorporating all ending-triggering transition and terminating in a preset manner with respect to the occurrence of the ending-triggering transition; and
transmitting a signal wave having a waveform made from the segments.

Abstract
RFID readers exchange information with RFID tags. The information is encoded for transmission and decoded upon reception. Encoding is in binary bits, which are in turn encoded in waveform segments. The last transmitted waveform incorporates an ending-triggering transition, and terminates in a preset manner with respect to when the ending-triggering transition occurs. Parsing while decoding can happen by waiting for the ending-triggering transition, and then waiting according to the preset manner. This way there is no ambiguity in the ending of the waveform, and no End Frame is necessary.
