Story

Our projects aim to make checking in and out of factory simpler and more efficient as sometimes in factory, the fingerprint sensor is not working well due to the working environment in factory and workers fingerprint are sometimes damaged and it causes the system to not recognize the fingerprint and hence causing a congestion in the queue.

We used a RFID sensor that requires anyone that wishes to enter to tap their card first and if the sensor recognizes the card UID, it will display access granted and a green LED will light up with a buzzing sound, after that the motor will turn that acts like a gate for workers to enter the factory. However, if the card UID is not recognized, it will display access denied with a RED LED.
