Attendance system using Raspberry Pi and NFC Tag reader

Picture of Attendance system using Raspberry Pi and NFC Tag reader
With my new toy Raspberry pi I've done several testing projects from
instructables, adafruit etc. But after a while it became boring and I've started looking for something actually useful for me. My previous playground was my new phone several weeks ago which came with new feature NFC reading. Thought and thought together gave me idea for attendance system for our small (family) company using NFC tags. The additional kick was my interest in those systems before, but discovering the cheapest are for around $750 I decided it is too much for such small company as 6 employees.
As I don't have any experience with "mature" attendance systems, I've decided only to implement basic features. These consist of logging incoming people, outcoming people, start and end of a break and deleting last inserted action (in case of mistype during logging).
All these actions are logged into local MySQL database from where I can display it and manipulate with my front-end application. Because the SD card is not such safe data medium, especially when loosing power unexpectedly, I'm uploading all data daily to my local server, where I keep backup in case of corruption of the SD card.
During normal operation of the logging station, display shows current date and time and calls for action selection. When you choose appropriate action on the keyboard, display shows selected action and calls for attaching the TAG to the reader. Also the LED under display also turns on.
When the TAG is read, the LED turns off and beep signal comes out the speaker. For a brief moment display shows action and name of the owner of the card. Then everything returns to the default state waiting for another entrance.
