This app is created for an official purpose currently being used in our College, in order to easily keep a track on students coming late to the college. The app data is synced with a remote server, where data is stored permanently.
- The user must authenticate himself first in order to start scanning
- The app provides a quick barcode scanner, with an option to enable flash
- In case of damaged camera/barcode, the user can manually enter student number and register a late entry
- On scanning or manually entering data, student details pops up with name, branch, admission year, image, & student no (which are stored in app's database to provide quicker access)
- In offline scenario, all entries are stored in app's database, & can be synced with the server afterwards
- The Settings page include the option to sync locally stored student details & late entry records and other options related to the user
