ABSTRACT
The advancement of technology for the past decade has definitely triggered the need
for developing more advanced devices. The traditional door lock system which
comprises of a physical key and lock is slowly fading away. Although it is still
considered efficient, a major key issue does occur which is the hassle of carrying a
set of keys around for each lock to be unlocked. In addition to that, the distribution of
keys in larger organisations could be costly. Thus, by developing a keyless system
whereby only mobile phones are needed to unlock our doors, it would definitely
reduce the cost tremendously and also increase flexibility in addition to providing
ease of unlocking doors. In this modern society, majority of people in developed
countries owns a smart phone as it has become an integral necessity which simplifies
our lives. Without a doubt, utilising this important device in developing a keyless
door locking system would provide an abundance of benefits because there is
absolutely no need for carrying any extra objects but only to make use of existing
devices which are our mobile phones.
