The HKCOS e-Logbook app allows Trainees and Fellows of Hong Kong College of Orthopaedic Surgeons(HKCOS) to record attendance easily for CME/CPD or training point. It also allows HKCOS Fellows to view their CME/CPD profiles. During the activity, the organiser will post a QR code at the venue for HKCOS Trainees and Fellows to scan and capture the attendance. The attendance records will be uploaded to the HKCOS e-Logbook system and confirmed by organisers accordingly.
