Communication device capable of performing wireless communication according to NFC standard

A non-transitory computer-readable recording medium storing computer-readable instructions for a communication device,

• wherein the computer-readable instructions, when executed by a processor of the communication device, causing the communication device to:
• receive a specific signal from a terminal device via a Near Field Communication (NFC) interface in a case where the NFC interface operates in a Reader mode of NFC standard and the terminal device operates in a Card Emulation (CE) mode of the NFC standard, the NFC interface being configured to perform a wireless communication according to the NFC standard;
• determine whether the specific signal includes install information which indicates that a predetermined application has been installed in the terminal device, the predetermined application being for causing the terminal device to execute a wireless communication with the communication device using specific information;
• change an operation mode of the NFC interface from the Reader mode to the CE mode in a case where it is determined that the specific signal does not include the install information;
• change the operation mode of the NFC interface from the Reader mode to a Writer mode in a case where it is determined that the specific signal includes the install information;
• supply information for installing the predetermined application in the terminal device to the NFC interface in a case where the NFC interface operates in the CE mode,
• wherein the information for installing the predetermined application in the terminal device is for identifying the predetermined application and is different from the specific information,
• wherein the NFC interface sends the information for installing the predetermined application in the terminal device to the terminal device in a case where the NFC interface operates in the CE mode and the terminal device operates in the Reader mode;
• supply specific information to the NFC interface in a case where the NFC interface operates in the Writer mode, wherein the NFC interface sends the specific information to the terminal device in a case where the NFC interface operates in the Writer mode and the terminal device operates in the CE mode;
• and
• after the specific information has been sent to the terminal device, execute a wireless communication with the terminal device using the specific information sent to the terminal device.

A method performed by a communication device, the method comprising:

• determining whether the specific signal includes install information which indicates that a predetermined application has been installed in the terminal device, the predetermined application being an application for causing the terminal device to execute a wireless communication with the communication device using specific information;
• changing an operation mode of the NFC interface from the Reader mode to the CE mode in a case where it is determined that the specific signal does not include the install information;
• changing the operation mode of the NFC interface from the Reader mode to a Writer mode in a case where it is determined that the specific signal includes the install information;
• supplying information for installing the predetermined application in the terminal device to the NFC interface in a case where the NFC interface operates in the CE mode, the information for installing the predetermined application in the terminal device is for identifying the predetermined application,
• wherein the NFC interface sends the information for installing the predetermined application in the terminal device to the terminal device in a case where the NFC interface operates in the CE mode and the terminal device operates in the Reader mode;
• supplying specific information to the NFC interface in a case where the NFC interface operates in the Writer mode, wherein the NFC interface sends the specific information to the terminal device in a case where the NFC interface operates in the Writer mode and the terminal device operates in the CE mode;
• and
• executing a wireless communication with the terminal device using the specific information sent to the terminal device, after the specific information has been sent to the terminal device.
