RANCANG BANGUN SISTEM ABSENSI DAN BUKA PINTU DENGAN ENGGUNAKAN RADIO FREQUENCY IDENTIFICATION

The room security system now also has a good security system by entering the employee
ID number on the tool provided next to the door when you want to enter the room. But the
security system opening the door is still not secure when the employee ID is known by many
people. In terms of time efficiency, it is still considered impractical because it uses employee
ID numbers and passwords which take a long time to find the right number. Radio frequency
identification (RFID) is a technology that uses communication via electromagnetic waves to
change data between a terminal and an object such as a product, animal or human product for
the purpose of identification and tracking through the use of a device called an RFID tag. In
the application of RFID for attendance and unlocking doors, this system makes it easy to
monitor and control employees who enter certain rooms that are considered private.
