Abstract
A method and system for self-checkout of items from a retail or non-retail establishment is disclosed. The system verifies security by comparing a measured physical characteristic of an item with the stored security characteristic for that item and determining if the measured physical characteristic is within an operator-modifiable tolerance range. The operator-modifiable tolerance range is different for different of items in the store. Moreover, a stored security characteristic of an item can be updated automatically. In addition, the system includes a dynamic-weight scale that reports a measured weight before the scale settles.
Claims11
A method of checking out items having item codes comprising:
- associating a first group of items with a first metric corresponding to a physical characteristic common to every item in the first group;
- assigning a first tolerance value to the first metric;
- determining a first tolerance range for the first tolerance value;
- associating a second group of items with a second metric corresponding to a physical characteristic common to every item in the second group;
- assigning a second tolerance value to the second metric;
- determining a second tolerance range for the second tolerance value;
- and
- applying a global tolerance variable to the first and second tolerance values.
