| - | I built this project because I wanted to make it easier for me to log into my computer. We have many types of verification methods these days, like password, pin, pattern, gesture, fingerprint recognition, face recognition and much more. The user will have very high security without having to type the password. It is going to be a device that securely unlocks the computer using a RFID tag. | + | I built this project because I wanted to make it easier for me to log into my computer.

The Arduino Board and RFID reader will always be connected to the computer. All that is needed is to sweep the RFID tag over RFID reader to unlock the system. The computer will log in after the Arduino sends the UID of the RFID tag to the computer. |

| + | In the void setup is initialized the serial, SPI communication and the RFID reader. | ||

| + | In the loop function is the search for the card. If the card is found, RFID tag data will be transferred to the system using serial print. This serial print value will be compared with the file that we placed earlier and if it a match the windows will unlock itself. | ||
