Student ID in Wallet
University of Alabama president Stewart Bell spoke about this:
We have actually been working on this project for some time a little bit under the cloak of secrecy. It is a next-generation technology program that will allow our students to have access to security issues and things they pay for.
Students will be able to gain access to campus locations such as the library, dorms, sporting events, etc., as well as buy snacks, pay for laundry, and get meals with their Apple Watch or iPhone.
The program is launching at Duke University, University of Oklahoma, and University of Alabama in September. This will be followed by John Hopkins University, Santa Clara University and Temple University by the end of the year.
