Apple:

Starting today, students at three universities are among the first to enjoy the convenience of using just their iPhone and Apple Watch to get around on and off campus. At Duke University and the Universities of Alabama and Oklahoma, students can now add their ID card to Apple Wallet 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.

This is a brilliant move, making iOS desirable for every new generation of students.
