Following a preview at WWDC 2018, Apple today announced that students at three universities in the United States can now add their student ID cards to Apple Wallet to get around campus using just an iPhone or Apple Watch.

Namely, starting today, students at Duke University, the University of Alabama, and the University of Oklahoma can now add their ID card to the Wallet app on iOS 12 and watchOS 5 and use it to pay quickly and easily for laundry, coffee or lunch, and even get into their dorms, the gym, or the school library.

Apple says Johns Hopkins University, Santa Clara University, and Temple University will roll out the capability by the end of this school year.

Students simply hold their iPhone or Apple Watch near the reader anywhere physical student ID cards are accepted — on and off campus. An optional Express Mode bypasses the need to authenticate with Face ID, Touch ID, or a passcode, allowing for the quickest entry possible to buildings around campus.
