After accessing your student profile on the Academic Portal, you must click on “Payments”, select the item(s) you want to pay and proceed by clicking on the button “Item(s) to pay”. After confirming, your order will be processed automatically and ATM references will be displayed on your screen. You can use these at any ATM machine or your home banking website. The ATM references generated will be valid for 48 hours. If you do not pay during this period, you must access the Academic Portal again and generate new references, following the steps mentioned above.
