Apple Pay is coming to the web.

Launched in 2014, Apple’s mobile payment service lets iOS device owners buy things inside Apple’s App Store, in native apps, and at physical stores using near-field communication (NFC). Soon, Apple says, the service will also support web payments, too.

But it’s going to do this in an interesting, safe way — if you find something you want on the web even while using your desktop, you’ll reach for your phone and put your fingerprint on the TouchID scanner integrated into the home button. It’s a clever implementation of two-factor authentication for purchases.

Also, Apple Pay is expanding its reach — soon it will be coming to France, Hong Kong, and Switzerland.

Today’s announcement was rumored last month.

Apple announced the news today during WWDC, its annual developer conference.
