This DIY tutorial is dedicated to the creation of a simple time and attendance system that utilizes a Phidgets RFID read-write and Raspberry Pi. Here the maker has used a web page for displaying present time along with a confirmation message for all employees. Incoming, as well as outgoing information, gets stored in a file. The basic requirements for this system include a Raspberry Pi 2 or Raspberry B+ or B, the latest Raspbian version, and preinstalled MicroSD Card 8GB Class 10 Raspbian.
To start with, connect the RFID reader with a USB Raspberry port and monitor. Not update the package and prepare the system with Phidgets for working. You can now install the chromium browser and clear the screen by removing the cursor from there. The chromium browser comes with a kiosk mode that results in full-screen display of the browser without any icons or taskbar. These are most suitable for the kiosk style screen.
Before anything is displayed on screen make sure you go through all setup steps and disable the non-required settings. First of all, disable the screensaver and all other energy settings so that the screen never goes to sleep while you are working on it. You can edit it by giving the command: edit file /e:c/xdg/lxsession/LXDE-pi/autostart.
Sudo nano/etc/xdg/lxsession/LXDE-pi/autostart is a file that is executed every time pi boots up. In order to disable the screensaver, just add # to its beginning. By giving a few more commands, you can then disable power management set up and cease the screen from blanking in every few minutes. Once, this is done you can move on to preventing all error messages that get displayed on the screen within a moment whenever the Pi is power cycled without shutdown procedure. Once this is done, you can tell chromium to start working and the page that you need to load without any error messages.
In order to ensure the raspberry pi boots up over desktop, you can always type the command sudo raspi-config. For GUI, RFID tags, and other programming details, check out the link given below.
