Method and apparatus for operating a security system of a self-service checkout terminal
First Claim
1. A method of operating a self-service checkout terminal, comprising the steps of:
- generating an item-entered control signal when a user enters an item for purchase with a code entry device;
disabling said code entry device in response to generation of said item-entered control signal;
generating an item-not-detected control signal if said user does not place said item for purchase in a post-scan area within a first predetermined period of time subsequent to generation of said item-entered control signal; and
enabling said code entry device in response to generation of said item-not-detected control signal.

Abstract
A method of operating a self-service checkout terminal having a scanner device for allowing a user to enter an item for purchase, and a weight scale for detecting placement of the item for purchase in a post-scan area associated with the self-service checkout terminal includes the step of generating an item-entered control signal when the user scans the item for purchase with the scanner device. The method also includes the step of disabling the scanner device in response to generation of the item-entered control signal. Moreover, the method includes the step of generating an item-not-detected control signal if the weight scale does not detect placement of the item for purchase in the post-scan area within a first predetermined period of time subsequent to generation of the item-entered control signal. Yet further, the method includes the step of enabling the scanner device in response to generation of the item-not-detected control signal. A self-service checkout terminal is also disclosed.

8. A method of operating a self-service checkout terminal having (i) a scanner device for allowing a user to enter an item for purchase, and (ii) a weight scale for detecting placement of said item for purchase in a post-scan area associated with said self-service checkout terminal, comprising the steps of:
-
generating an item-entered control signal when said user scans said item for purchase with said scanner device; disabling said scanner device in response to generation of said item-entered control signal; generating an item-not-detected control signal if said weight scale does not detect placement of said item for purchase in said post-scan area within a first predetermined period of time subsequent to generation of said item-entered control signal; and enabling said scanner device in response to generation of said item-not-detected control signal. - View Dependent Claims (9, 10, 11, 12)

13. A self-service checkout terminal, comprising:
-
an entry device for allowing a user to enter an item for purchase; an item sensor for detecting placement of said item for purchase in a post-scan area associated with said self-service checkout terminal; a processing unit electrically coupled to both said code entry device and said item sensor; and a memory device electrically coupled to said processing unit, wherein said memory device has stored therein a plurality of instructions which, when executed by said processing unit, causes said processing unit to; (a) generate an item-entered control signal when said user enters said item for purchase with said code entry device, (b) disable said code entry device in response to generation of said item-entered control signal, (c) generate an item-not-detected control signal if said item sensor does not detect placement of said item for purchase in said post-scan area within a first predetermined period of time subsequent to generation of said item-entered control signal, and (d) enable said code entry device in response to generation of said item-not-detected control signal. - View Dependent Claims (14, 15, 16, 17, 18, 19)
