The main gate of any gated community is the busiest and probably the most chaotic location of a community. In any typical day, the main gate would open about a hundred to thousand times in a day – for cabs, resident vehicles, water tanks and visitor vehicles to move in and out. Hence, for a community of about 500 flats, vehicle management does become a serious concern. Many gated communities have installed Radio frequency Identification (RFID) based boom barriers, in an attempt to manage the vehicle movement in their society. However, there are certain aspects of this solution that every community must know before installing an RFID based boom barrier.
RFID is a small chip (about 2,000 bytes of data) and an antenna that is placed together on an electronic device (in this case, boom barrier). RFID is used to establish a unique identity for an object that is scanned to obtain the information. In gated communities, these devices are majorly used with boom barriers to manage vehicle movements and differentiate between resident and visitor vehicles.
The basic working of an RFID based boom barrier
All the resident vehicles have to first register with the management committee and get a RFID tag placed on their vehicle. An RFID reader tag is installed on the boom barrier, which is placed at the entrance of the community. When a car is about to enter the community, the RFID tag on the vehicle is read by the reader tag on the boom barrier and the boom barrier opens, letting the vehicle in. In case of a vehicle that is not registered with the community, the boom barrier will not open.
