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.
