What is a smart padlock? Key features and benefits at a glance

A modern solution for secure access
Traditional padlocks have long been used to secure gates, containers, and equipment. But in today’s fast-paced and digitally connected world, they often fall short.

What makes a padlock “smart”?
A smart padlock replaces physical keys with secure mobile access. Using NFC technology, it draws power from a smartphone or key fob, eliminating the need for batteries or wiring. This makes it ideal for remote locations and harsh environments where maintenance is costly or impractical.

Advanced security
Smart padlocks use AES-256 encryption and provide real-time access logs. Access rights can be granted or revoked instantly, ensuring only authorised users can unlock them.
Mobile access
Users unlock padlocks with their smartphones, removing the need for physical keys. This simplifies access management and reduces the risk of lost or stolen keys.

Administrators can manage access remotely via a secure platform. Whether for contractors, temporary staff, or multi-site operations, control is centralised and efficient.
