Each lock passes access to only one RFID card, so all other cards are denied access. The system can also be programmed to provide additional access to a master card, which may be used instead of a ...

This project presents the design and implementation of a secure RFID-based access control system using Arduino UNO and MFRC522 RFID module. The system grants access only to authorized RFID cards and ...

[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

Electronic and Arduino enthusiasts searching for an Arduino project to keep them busy this weekend may be interested in a new Arduino Mega fingerprint door lock. Using a little Arduino programming the ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

When it comes to security, RFID card-based digital locks are more reliable than key-based mechanical locks since they cannot be easily broken. Also, they are Contactless Lock, therefore, some hotels ...

Abstract: In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present ...

Abstract: Among the many potential applications of inexpensive radio frequency identification (RFID) technology are security, tracking assets, people monitoring, supply recognition, and access control ...
