Current features:
1. Two step setup
No need for specialized devices. You can quickly set up the system just by using any Android smartphone

2. QR Code cards
From the app, you can export a ready-to-print PDF containing employees QR cards

3. Two-factor authentication
PIN code adds a layer of extra security for the QR authentication. Also, as an alternative, the employee can punch using user/pass credentials

4. .xls data export
You can obtain the punching data just by exporting a .xls file. Besides the raw data, the file also contains a synthesized report of employee working hours

Future development:
1. NFC cards authentication
2. Fingerprint authentication
3. Image capture on scan (to prevent buddy-punch)
4. More reports on employee time
5. Configurable alarms
You get notified when for example an employee misses work or arrives too late at work.
