No, I did not. But what if it happened?
In the incident of you ever forgetting your card at home, and there is no chance in actually going to get it before class starts, you should do the following:
Go to Borough Road Building and ask for a temporary card at the reception. Worth noting here is, you can only get three one-day passes, so do not make a habit of forgetting it!
If you by chance would happen to actually lose your card, it gets even worse! Mostly. This is what to do:
Go to Bourough Road Building and tell the staff you have lost your card. In my head the staff then laughs at you, but I believe they act far more professional than that, and tells you what to do. The place to go from there is room LR102, which is the security office, where you once again should say you have lost your card (this should be done immediately!). To issue a new card you will be charged £10.
In the highly unlikely event of someone not getting why this card is of importance, I will now tell you why.
IT IS VERY HARD TO GET ANYWHERE WITHIN THE FACILITIES WITHOUT A STUDENT ID CARD!
With that said, it is used to access most of the rooms and other points of interest by the university, to open the gates. Of course you can simply jump over the gates, but that is why we have guards at them as well.
If you still would manage to get to a session, you also need your card to log your attendance, and use the library and probably some other cool stuff I have missed.
With that said, keep your Student ID Card with you on all times, it will significantly benefit you in your studies.
Best of luck!
