This weekly report summarizes the progress of the KID-WA company engineering team. This week, the team studied the transmission of RFID (radio-frequency identification) and how radio waves are used to transmit data from tags attached to objects to interrogators or readers connected to an RFID system. The team analyzed the strengths of RFID being widely used in the future and did not find any weaknesses. Next week, the team will study transmitting additional information using RFID.

Weekly Progress
This week, we have studied the transmission of RFID. To transmit data using radio
waves to transmit data is sent. A radio-frequency identification system uses tags, or labels
attached to the objects to be identified. Two-way radio transmitter-receivers called
interrogators or readers send a signal to the tag and read its response. The readers
generally transmit their observations to a computer system running RFID software or RFID
middleware. The tag's information is stored electronically in a non-volatile memory. The
RFID tag includes a small RF transmitter and receiver. An RFID reader transmits an
encoded radio signal to interrogate the tag. The tag receives the message and responds
with its identification information. This may be only a unique tag serial number, or may be
product-related information such as a stock number, lot or batch number, production date, or
other specific information.
