Abstract
The RFID Door Lock is a lock that is simple to install and allows the user to
easily lock and
unlock doors. It will contain a RFID reader/writer and a magnetic door lock for simple use.
All the user
will need is an RFID tag to be able to unlock and lock the door. A LED will be used
to let the user know
when the door is in fact locked. The components included in the module are small and compact.
Additionally, the door lock is simple and easy to install. It does not require the consumer to disassemble
the door or doorframe as the door lock are merely attachments. This is also leaves the consumer with the
option of using their original lock and key if they so choose. All in all, this RFID door lock should be a
simple and cost effective upgrade to the average consumer’s security and convenience.
