Tags can be read-only or read-write.
Tag memory can be factory or field programmed, partition-able and optionally permanently locked.
Bytes left unlocked can be re-written over more than 100,000 times.
An active tag has an on-board battery and periodically transmits its ID signal. A battery assisted passive (BAP) has a small battery on board and is activated when in the presence of a RFID reader.
The simplest passive RFID tags do not have batteries or transmitters. They get their energy from the field of the reader. They transfer their information to the reader by modulating the signal that is reflected back to the reader by the tag. Because tags depend on the reader for power their range is limited, typically up to 10 meters or 30 feet for UHF RFID tags.
