By the time Apple introduces its much-anticipated mixed reality headset—planned for sometime next year—Meta Platforms will have had the advantage of selling products in the category to the public for almost seven years. But Apple’s device will also have a few technological tricks up its sleeve that even the latest Meta headset can’t boast of.

For example, Apple’s device is expected to have the ability to scan the irises of people wearing the headsets so they can quickly log into their accounts simply by putting the devices on their heads, according to two people who helped develop the Apple headset. The capability will make it easier for multiple people to use the same device and allow them to quickly make payments inside the headset, just as iPhones allow people to confirm payments using scans of their fingerprints or faces, the people said.
