Log employee arrival and departure with and attendance logger using Arduino. via instructables
I was designing attendance logger for local company and immeditally saw potential in this simple logger. First prototype was made with Arduino and was only a proof of concept. Because of that company allowed me to share this project.
System that company is using today grew up Arduino’s performance and got many more features today.
RFID module was used in initial phase of development. NFC module could be used instead.
