ABSTRACT:
A non-contact IC card comprising a circuit board (10), an electronic circuit (9) mounted on the circuit board (10) and having a plurality of functions, a package (14) sealing the electronic circuit (9), a plurality of testing wire conductors (8) disposed on the circuit board (10) and connected at one end to the electronic circuit (9) and exposed at the other end from the package (14) for individually testing the functions of the electronic circuit (9). Each of the other end of the testing wire conductors (8) comprises a testing pad (11) disposed on the circuit board (10). The non-contact IC card may comprise insulating means electrically insulating the other end of the testing wire conductors or the testing pads (11) from outside.
The present invention also resides in methods for manufacturing and testing the same.
