Amazon is expanding its palm-scanning technology beyond grocery stores and is rolling out a version that's designed for the business world.
Companies already signed up for the biometric technology include IHG Hotels and Resorts, turnstile manufacturer Boon Edam, and Kone, an escalator and elevator provider.
Amazon didn't disclose pricing for the service, which is available in preview in the U.S. starting Monday.
Advocacy groups have criticized the service over privacy and security concerns, arguing it leads to increased surveillance.
Earlier this month, Amazon debuted Astro for Business, a version of its household robot that it's framing as a roving security guard for businesses.
