It can also be carried onto an aircraft (meets RTCA standards). You can set, measure, record, and check by simply bringing it close to an NFC communication reader (a separate computer with a FeliCa port is required). Data is read using NFC communication (FeliCa), making it easy to check the contents and send the data to the server. The smartphone app and PC software can be downloaded for free from http://f-log.jp/, and the Android device (with NFC function) app can be downloaded for free from https://play.google.com/store/apps/details?id=watch_logger.appli＆hl=ja.
