What is RFID?
Radio Frequency Identification (RFID)
Wireless transmission of information between
transponder and reader without visibility
Bidirectional transfer (read and write)
Transponder (tag) can be attached, embedded or
implanted
Automatic correlation between object and saved
data
Generic Terms
RFID is often used as generic term for complete
infrastructures.
A transponder (aka RFID-chip, -tag, -label, wireless label
or simply chip)
A reader (in fact most of them can write to the tag too)
Some middleware, which connects the reader to a server
Some communication infrastructure
Integration with server farms, data warehouses, services
and supporting systems
