Why do I get an "Invalid card number or PIN" message when I try to log on?

You may have incorrectly typed your Library barcode number or your Library card could be expired. Note: it is necessary to have a valid 14-digit library card starting with the numbers 22950, and a PIN (personal identification number). Your PIN is usually the last 4 digits of your phone number. Ensure that the Num Lock key (on the keyboard) is on before entering your Library card number. If you still get an "Invalid card number or PIN" message, please talk to Library staff.
