Each Smartcard is unique and is intended to last the duration or your course or contract. However, misuse of your card may result in its failure to operate.
Please treat your card as you would a credit card i.e. do not bend or flex the card etc. A failed card will cause you inconvenience until it can be replaced and you may be charged £10 to obtain a new one.
If you lose your Smartcard, it could cost you a lot (if for example, someone else uses it to borrow books which are not then returned to the Library).
See here for further information about replacement cards.
