Basic System Operation
The C•CURE Watch system consists of three
major parts: transponder (embedded in tag or
card), antenna, and RF controller.
To read data from a tag/card, the RF controller
transmits a 134.2kHz charging field for
approximately 50ms to an antenna connected to
the RF controller. The electromagnetic field
generated by the antenna charges the tag/card.
The tag/card stores this charge in a capacitor.
After the 50ms charging period ends, the tag/card
immediately transmits its pre-programmed data for
20ms, using the energy stored in the capacitor as
its power source. Once all the data is transmitted,
the storage capacitor is discharged, and the
transponder is reset, readying it for the next power
pulse.
