FamilyNet Japan (FNJ) announced that it obtained a patent on September 1st for its "Direct Delivery" service, which delivers products directly to the front door of apartment buildings.
The acquisition of this patent is expected to significantly contribute to improving the safety and convenience of residents, streamlining and promoting digital transformation in condominium management operations, and strengthening resilience during disasters.

This service uses timed authentication keys to unlock the automatic locks in common areas, allowing only authorized service providers (such as delivery companies) to enter the building. Because the management company can remotely issue timed authentication keys, urgent maintenance workers such as cleaners and inspectors can enter without requiring their presence. This contributes to reducing the manpower required for management operations. Since the verification of timed authentication keys does not depend on the communication environment, entry and exit are possible even during disasters or network failures. This contributes to strengthening the resilience of the apartment building.
Using a patented proprietary algorithm for verifying the timed authentication key used upon entry, the system achieves highly accurate and reliable authentication and unlocking, independent of the building's communication environment. The system issues one-time passwords via a 2D barcode, making duplication and tampering extremely difficult, providing a high level of security unattainable with typical PINs or shared keys.
In particular, the technology of "offline authentication × key generation using 2D barcodes" is the core of the patent, and it is a highly unique mechanism that is difficult for similar services to imitate. This enables safe and reliable operation even in the event of disasters or communication failures, and overcomes the problems that could not be solved with physical key management.
The Ministry of Land, Infrastructure, Transport and Tourism is considering legal revisions, including security measures for "leave-at-door" deliveries, with the aim of reducing the burden on logistics operators and decreasing redeliveries by the end of March 2026. "Direct Delivery" is attracting attention because it can respond to these policy trends and social movements and provide a safe and secure "leave-at-door" delivery environment.
FNJ states that it will continue to provide solutions through its "Direct Delivery" service that address social issues such as reducing environmental impact by decreasing redeliveries, contributing to a decarbonized society, promoting digital transformation in management operations, and resolving labor shortages.
