Abstract:
1. An article comprising: a printed wiring board; a contact hole formed in the printed wiring board; an IC chip on a first side of the printed wiring board comprising: a first terminal and a second terminal on the first side of the printed wiring board; a third terminal on a second side of the printed wiring board; and a wiring over a substrate, wherein the printed wiring board is attached to the substrate so that the first side of the IC chip faces the substrate, wherein the IC chip is electrically connected to the first terminal through a first wire and to the second terminal through a second wire, wherein the first terminal is electrically connected to the third terminal via the contact hole, wherein the second terminal is electrically connected to the wiring by an anisotropic conductive film, wherein the IC chip is configured to compare the second piece of information with a third piece of information sent from an external device, wherein the IC chip is configured to transmit the first piece of information to the external device in a case where the second piece of information is the same as the third piece of information, and wherein the IC chip is configured to terminate communication between the IC chip and the external device in a case where the second piece of information is different from the third piece of information.
