Comparative Evaluation of NFC Tags for the NFC-Controlled Door Lock with Automated Circuit Breaker

摘要

In the age of automation where almost all household appliances are having the term “smart”, the need for a secured door system together with an automated circuit breaker is indeed a must have for being in the trend. With the use of the NFC technology, entering door hassle-free without countless keys and open any door with just a tap of a single card is possible. The NFC-Controlled Door Lock also comes with an automatic circuit breaker that activates when a person entered, and it deactivates when the person exits therefore reducing power costs due to idle appliances. Moreover, 4 NFC tags/cards were tested for its detection speed and distance to determine the most suitable tag to be used. The system prototype is evaluated, and it is 100% accurate when recognizing and authorizing an NFC card. It also comes with a database that records the person who enters and exits the room which is accessible easily thru a browser-based database.
