An ingestible dosage form includes a pill containing a pharmaceutical
content and an RF tag associated with the pill. The RF tag is configured

signal received by the RF tag from an RF reader. The ingestible dosage
form includes memory for storing pill identifying information. The
wireless response signal includes the pill identifying information which
may be received and processed by the RF reader. A system for monitoring
patient medicine intake compliance includes a monitoring device placed
within communicative proximity of ingestible dosage forms to transmit the
wireless excitation signal and receive the wireless response signal
including pill identifying information from the ingestible dosage forms.
A device for determining an identity of a pill and quantity thereof
