South Korean steel giant POSCO has put ICONLOOP’s DID-based entry verification system to work at its hub offices in Seoul.

According to ICONLOOP on Monday, ICONLOOP turned POSCO’s two “With POSCO Work Station” offices in Seoul’s Yeouido and Euljiro districts into “smart offices” using the blockchain-based DID platform to control who gets in.

According to ICONLOOP, the system runs on the ICON public chain.

Using the new system, POSCO employees can easily verify who they are and enter the offices using a mobile phone without entry cards for each building.

DID technology enables people to verify their identity in a completely non-contact way while maintaining direct control over their personal data.

In this case, POSCO employees can use the technology to enter a hub office by proving they work for the company without turning over a ton of other unnecessary personal data.

ICONLOOP’s CEO, JH Kim, said companies need trustworthy entry control systems as more and more open remote work stations in the “non-contact” era.

He added that ICONLOOP would continue to put DID-based verification systems to work in a variety of places to enable people to enter facilities in a safer and more convenient manner.

Of course, this isn’t the first time ICONLOOP has partnered with POSCO, one of the world’s biggest steelmakers and a major player in Korea’s science and technology sector.

Earlier this year, the blockchain company installed its DID-based ID verification system at POSCO’s new startup space in the southeastern industrial city of Pohang.
