Secure opening

Direct4.me is using an OTP (One-Time-Password or One-Time-Key) generator in the backend, which is synchronized with the smart lock in our D-Spaces.

When any user requests a key to open D-Space, a One-Time-key is generated in the backend, encrypted, and prepared to be sent via a selected proximity channel (Data Over Voice, NFC, Bluetooth). On the side of D-Space, the key is decrypted and verified. In case key matches, D-Space will open.

  • Grant access The user's phone is granted access to Space.
  • Grant token User's phone obtains the right to the unique digital token.
  • Embed token A digital token is embedded into sound to form a so-called Sound Key.
  • Deliver Sound Key Sound Key is delivered to Space via phone's speaker to Space's microphone.

Patented Data Over Voice

Direct4.me native ways to distribute one-time-keys to open D-Spaces is sound. The key is modulated in sound, encrypted, and can be sent:

Via data (internet) channel to mobile app or website

Triggering a D-Space opening act in a mobile app sends a request to the Direct4.me Platform to generate a one-time key. It is modulated in a sound file, encrypted, and sent as a voice file to the mobile app, where it is played toward a smart lock on D-Space, which will detect the key and initiate D-Space opening if keys are matching.

Through a regular phone call

On establishing a voice call to the Direct4.me Platform, a one-time key in the form of voice (sound) signals are sent to the smart lock on D-Space through the customer's mobile phone. The smart lock detects the key and initiates the opening process if the keys are matching.
The customer’s phone thus serves as a communication device between the Direct4.me Platform and D-Space. They communicate in the same manner as people do – using speech and a mobile phone.

Data-Over-Voice is a patented technology proven in other industries like mobile payments, mobile wallets, mobile loyalty, and public transport ticketing systems with over 1.8 billion transactions.

Bluetooth and NFC

One-Time-Keys can be distributed via Bluetooth or NFC as well.

The principle of One-Time-Key verification is always the same, only the proximity channel differs. To use Bluetooth or NFC the use of a mobile app and user registration is essential.

Power saving architecture

All Direct4.me D-Spaces are battery operated, which creates numerous advantages of installing parcel lockers. No special preparation is required.

Direct4.me D-Space architecture is focused on energy saving; the smart lock is in sleep mode throughout the time and only wakes up when the proximity sensor detects a user attempting to open D-Space. ePaper display is also a very efficient solution as it requires power only to refresh the screen.

The power-saving architecture enables up to two years of operations for D-Spaces and up to five years for MultiSpaces.
