A first communication apparatus may comprise a first type of interface configured to function as an IC tag, a second type of interface, and a controller. The controller may cause the first type of interface to execute a sending operation. The sending operation may be executed by using a first wireless connection established between the first and second communication apparatuses. The sending operation may include an operation of the first type of interface to send network identification information to the second communication apparatus. The network identification information may be information to be used in a first wireless network to which both the first and second communication apparatuses belong. The controller may execute, after the first type of interface has executed the sending operation, a wireless communication of target data with the second communication apparatus via the second type of interface by using the first wireless network.
