Abstract: An electronic apparatus is worn on a body of a user. At least one processor determines whether biological information of the user contains an abnormality. An abnormality notification screen is displayed on a display when the at least one processor determines that the biological information contains the abnormality, the abnormality notification screen notifying an abnormality in the user.

Abstract: An electronic apparatus includes a communication unit and at least one processor. The communication unit communicates with an IC chip of a communication device to obtain information in the IC chip. The at least one processor performs processing based on obtained information being obtained by the communication unit. The at least one processor discards the obtained information if the communication unit becomes unable to communicate with the IC chip.

Abstract: A communication apparatus includes a first connector, a communication unit, and at least one processor. The first connector is configured to be attachable to and removable from a second connector of a portable telephone to which a cable is attached in transmission and reception of data to and from another device. The communication unit is configured to convert data into a radio signal and transmit the radio signal and to convert a received radio signal into data. The processor is configured to receive data from a portable telephone through the first connector, output the received data to the communication unit, receive data converted by the communication unit, and output the received data to a portable telephone through the first connector.

Abstract: A mobile phone includes: a first display provided in a front surface of a cabinet, the first display requiring electric power to keep displaying an image; a touch panel configured to detect an operation performed by a user onto the first display; a second display provided in a rear surface of the cabinet, the second display requiring no electric power to keep displaying an image; and a control module configured to control the first display and the second display. The control module is configured to: display an image on the first display in accordance with the user's operation and turn off the first display when the user's operation has not been detected by the touch panel for a predetermined time; and display predetermined information on the second display, the predetermined information being able to be seen by the user when the first display is off.
