The method includes creation of a mail item record that identifies the item and includes the weight. Mail items may be weighed by determining a first scale weight reading, introducing a mail item onto the scale, determining the mail item weight at one or more times within a time window, and finding the difference between each consecutive scale weight. Differences between scale weight readings not equal to zero are outputted. All outputted scale weight readings are totaled to obtain the mail item weight. Further disclosed are a mail processing system and a method of ceasing mail processing when invalid weights are detected.
