News Summary

• Researchers from several universities in China have developed a technology they called AccLock.
• It's a way of verifying your identity using your heartbeat, as detected by your earbuds.
• In testing AccLock, the researchers did in fact use AirPods, as well as their own custom-made earphones, and so it clearly could work within Apple's system.
• But it doesn't have to, because it only relies on motion-sensing tech rather than a dedicated heart-rate tracker.
