Abstract
The present invention provides a kind of contactless electromagnetic identification code IC circuit, which contains a control circuit to detect an input pad, and to provide a coding signal to decide one identification code for the contactless electromagnetic induced identification code IC. The control circuit contains: a carry clock signal source, which provides a carry clock signal to the input pad for generating a responding signal from the input pad; and a flip-flop set, which connects to the input pad, decides the identification code and forms the coding signal according to the pad'"'"'s responding signal and the carry clock signal.
