We can replace existing locks on hotel rooms, houses, or units with electronic locks that utilize fingerprint and keypad identification. Each lock will connect to the cloud through modems using powerline communication (PLC), allowing remote modification of access rights at the respective offices.

For instance, in public housing scenarios, tenants must register their fingerprints and key codes at the Department of Housing and Public Works office. In the case of hotel rooms, the front desk will manage guest fingerprint registrations, ensuring that only registered guests are granted room access.

. 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


If a tenant/guest has dirty hands or finger injuries, they can use the electronic keypad to enter their unique code, which is registered at the office/front desk. In the case of a hotel maid needing access to multiple rooms, a special code for the maid service can be used with the keypad.

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

Once we select the database type, we can decide which software will offer the most effective solution for managing user accounts. Additionally, we can determine the number of various account types needed based on the access requirements for each user type.


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 installed, new tenants or guests can update their access at the office or front desk. 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 store fingerprints, enabling departing tenants to access future residences without visiting an office. The decision rests with the Department of Housing and Public Works or hotel management, considering privacy and other factors. Freelance Robotics ensures the locks can store a minimum of 50 fingerprints, eliminating the need for tenants or guests to remember specific fingers.

Access for emergency and health support workers will be provided by the pin pad on the lock. Pins will be managed using the existing system, providing direct access to residences without the need for lockboxes. This ensures quicker access for workers and eliminates the risk of key misplacement, reducing administrative overhead. Each lock will transmit activation data to the server. Authorized staff can access this data to monitor door activity, helping identify potential tenant or guest well-being concerns.
