ABSTRACT:
A method of resetting a product scale of a retail checkout terminal includes the step of detecting absence of an item on the product scale. The method also includes the step of generating an absence signal in response to the detecting step. The method further includes the step of determining a first idle value with the product scale. The method also includes the step of comparing the first idle value to a reset value. Moreover, the method includes the step of generating a first control signal if the first idle value matches a reset value. The method also includes the step of generating a second control signal if the first idle value does not match the reset value. Yet further, the method includes the step of resetting the product scale in response to generation of the second control signal. An apparatus for resetting a product scale of a retail checkout terminal is also disclosed.
