1. A system to collect and transfer data wirelessly using a Radio Frequency Identification (RFID) communication protocol, comprising:
- a sensor and near field transceiver circuit, including;
a data measurement module;
a near field transceiver module; and
an antenna;
at least one tag; and
a RFID reader;
wherein said data measurement module is configured to periodically sense a condition, generate data based on the condition and transfer the generated data to the near field reader module;
wherein said near field transceiver module is configured to format said generated data according to a Radio Frequency Identification (RFID) protocol and transmit said formatted data to at least one tag via said antenna according to the RFID protocol; and
wherein said reader is configured to read said formatted data from said at least one tag according to the RFID protocol.

Abstract
Methods, systems, and apparatuses for wireless communication using a Radio Frequency Identification (RFID) protocol are described. The system includes a sensor for sensing a condition and converting it into electrical signals. The sensor is coupled to a near field transceiver. The near field transceiver formats the data collected by the sensor and transmits it wirelessly using an RFID protocol to a tag. A reader uses the RFID protocol to wirelessly read the data from the tag.
