RFID (Radio Frequency Identification) Application for Door Security Systems

Abstract

The door security system is an important thing which is quite a complicated problem, especially in big cities. A door security system is required to have higher security, due to the many cases of theft and burglary because it is not properly protected. In order to overcome this problem, in this research a prototype design for a door security system based on RFID (Radio Frequency Identification) will be created. RFID card testing aims to determine the ability of the RFID reader in the process of reading RFID tags in the form of cards from various distances. The distance from the registered RFID card has different capabilities to be read by the RFID reader. The maximum distance that the RFID reader can successfully read is 1.5 cm with a delay of 1.58 s. Meanwhile, the minimum distance that can be successfully read by an RFID reader is 0 cm with a delay of 1.13 s. Therefore, we can draw the conclusion that the best position for RFID reader users who will carry out the RFID scanning process is to place the RFID tag at a distance of 0 cm. This is because the closer the distance between the RFID reader and the RFID tag, the stronger the radio signal emitted will be.
