Interesting news out of Chicago's Fulton Market District. A multi-tenant office building, 167 Green Street, has made electronic badge access available to all working in the building. Developers Shapack Partners and Focus, with real estate investment firm Walton Street Capital, claim that this is the "first multi-tenant office building in the United States to offer all tenants building access through employee badge in Apple Wallet," according to a press release.

Tenants can "seamlessly and securely tap their iPhone or Apple Watch to unlock office doors, turnstiles, elevators, and key card-protected amenity spaces – eliminating the need to open an app or present a traditional plastic access key," the firms explained. "Even if a user's iPhone needs to be charged, they will still be able to access the building for up to five hours after with Power Reserve."

Two companies are behind the technology. Sharry, a European proptech company, specializes in "touchless access" and "reception management," according to its website. Sharry claims that it integrates with more than 20 access control systems and is in use across 40 million square feet of facilities on three continents.
