It is batteryless because it gets the energy as its power from an external coil in an electromagnetic field. It gets the clock from the electromagnetic field and read the data from internal preprogrammed poly fuse ROM. By turning On/Off the modulation circuit, the T8200 send the back scattering data to a read device.
