All PhD Students have their own institutional badge, issued upon matriculation.
This is a personal magnetic card, valid for the entire duration of the PhD programme, that allows access to the university structures, such as libraries and laboratories, once activated by the department concerned, also to departmental facilities.
Issuing of badges
You can print your badge using the QR code sent to your nome.cognome@studio.unibo.it account at one of the self-service machines available in the university. 
Lost, stolen, damaged or de-magnetised badges
If a badge is lost, stolen, damaged or de-magnetised, the PhD Student may request a replacement by writing to aform.udottricerca@unibo.it and attaching:
After submitting the application for a replacement, upon payment of the duplicate fee of € 10, to be made on the Studenti Online application, a new QR code will be issued.
Returning the badge at the end of your career
The badge must be returned to the department concerned following completion of the PhD programme, or withdrawal.
