A class of RFID tag that contains a power source, such as a battery, to power the microchip’s circuitry. Active tags transmit a signal to a reader and can be read from 100 feet or more away. This class of tag is also known as a battery-assisted tag.

Amplitude Modulation [ AM ]
Representation of data or signal states by the amplitude of a fixed frequency sinusoidal carrier wave. Where data is in binary form the modulation involves two levels of amplitude and is referred to as Amplitude Shift Keying (ASK).
Amplitude Shift Keying [ ASK ]
Representation of binary data states, 0 and 1, by the amplitude of a fixed frequency sinusoidal carrier wave. Where the amplitudes are determined by the carrier being switched on and off, the process is known as On-Off Keying (OOK).
Antenna
The conductive element that enables an RFID tag or tags to send and receive data.

Automatic Identification and Data Capture [ AIDC ]
Technology associated with the creation and acquisition of machine-readable data. The primary technologies are bar codes and Radio Frequency Identification (RFID).
Backscatter Modulation
A process whereby a transponder responds to a reader/interrogation signal or field by modulating and re-radiating or transmitting the response signal at the same carrier frequency.
