Division 54 Convention App is a non-commercial app created to record the log in and log out time of the attendees during the SPP Annual Conference. Each conference has several sessions. The participants can earn CE credits by attending some of them. There is an attendance percentage that they need to meet to be eligible for the CE credits and this app records the log in and log out time to do the calculation. The app only records the log in and log out time of each participants and sends the information to the Convention Management Portal (http://convention.societyofpediatricpsychology.org/). All the calculation is done in the portal. The participants are given an ID card with unique QR codes embedded on them. They need to show the card to the app while entering and exiting a session. The app records the enter and exit time of each user and sends the information back to the Convention Management Portal.
