False Rejection or False Negative

Now imagine that Sally has the same laptop.  She has registered her fingerprint on the system.  The next day she tries to use this for authentication. Unfortunately, the system rejects her fingerprint. It returns a negative match as though Sally's fingerprint isn't actually her finger even though it's the same finger she used the day before.
