Existing locks can be removed on each hotel room, house or unit and replaced with electronic locks which use fingerprint and keypad identification. Each lock will be connected to the cloud via modems using powerline communication (PLC), enabling remote changing of access rights at the respectable offices. For example, in the instance of public housing, tenants will be required to register their fingerprints and key code at the office of the Department of Housing and Public Works. In the instance of hotel rooms, the front desk would be responsible for guests registering their fingerprints and therefore, room access can only be granted to registered guests. This has the potential to be extremely valuable for larger hotel chains to keep records of each guest, which hotels they stay at and how regularly they travel, allowing hotel management to provide unique specials to those guests based on their travel behaviours. Once a guest has had their fingerprints registered the first time, their fingerprint can stay on file with the hotel meaning they will not have to register their fingerprints a second time, only providing identification to the front desk.

Keyless Entry System


In the event a tenant/guest has dirty hands or has injured their fingers, with the addition of the electronic keypad, the guest can enter their unique code which is also registered at the office/front desk. Should a hotel maid wish to gain entry to a series of rooms, the keypad can be utilised with a special code for the maid service.

Our solution consists of four main components:

  • Database and server
  • Secure connection and login
  • Access accounts
  • Door lock system




Database and Server

Freelance Robotics is able to assess the current database and server arrangements in use by the respective office to determine whether they will meet future needs. If a change is needed, we can recommend a suitable database type and server service provider. We are also able to make arrangements to transfer current database information to the new system as necessary.

Connection to the database will be managed through one of the many PHP frameworks available. We anticipate using the “Bootstrap” library as this improves application development by employing reliable and well tested modules, allowing rapid development with assured support.


Secure Connection and Login

Staff will be able to connect with a secure login via HTTPS. SSL allows sensitive information such as credit card numbers and login credentials to be transmitted securely. Normally, data sent between browsers and web servers is sent in plain text, leaving it vulnerable to eavesdroppers. SSL certificates have a key pair – a public key and a private key. These keys work together to establish an encrypted connection. The certificate also contains what is called the “subject”, which is the identity of the certificate/website owner.


Access Accounts

After the database type has been selected, we can determine which software to provide the best solution for management of user accounts. We could also determine the number of different kinds of accounts that will be required based on the access which each type of user requires.


Door Lock System

Freelance Robotics can develop installation kits for the door lock system that allow suitably qualified tradesmen to change the door locks, such as cabling, modem, lock, and so on.

Electrician, electrical work

Once the system has been installed in the network of rooms or houses applicable and when a residence/room requires a change of access, the new tenant or guest will attend the office or the front desk to have their fingerprints recorded and access to the residence or room updated. Staff can login to the system, remove the old access and add the new fingerprints. These will be stored locally in the lock so that it can operate even without an internet connection. If desired, the system can have the capacity to store fingerprints so that a departing tenant could have their prints on file, allowing them access to a future residence without attending an office. This is the decision of the Department of Housing and Public Works, or the hotel management, depending on privacy and other considerations. Freelance Robotics can ensure the locks hold a memory of at least 50 fingerprints to allow multiple prints to be stored, negating the need for tenants or guests to remember which finger to use.

Access for emergency and health support workers will be provided by the pin pad on the lock. Pins will be managed using the system already in place, but will allow direct access to the residence rather than requiring the use of lock boxes to secure keys. This means that these workers will have quicker access and also removes the possibility that they will inadvertently misplace keys with the associated administrative overhead. Each lock will send data through to the server each time it is activated. The staff with appropriate access credentials will be able to access this data and be able to detect when doors aren’t being accessed, identifying potential concerns about the tenants or guests well-being.
