I don't know how many people are aware of this but I thought I would post as there are a lot of new starters at the minute! A lot of the places on campus you can't use your bank card to purchase food or drink!
The way the university gets round this is that you can link your bank card to an app called Yoyo Wallet which is on both Apple App Store and Google Wallet, the benefit of using the app however is its like a reward card? As in when you use it you save up points for fruit, muffins or even baked potatoes! You can even use the app to pay for Starbucks in the MX building!
